TMOD LOADER will NOT launch.

I have went to every forum, git hub page, reddit thread. It feels like I have tried everything. I've attached all of my logs from the folder, If anyone has any insight I would appreciate it so much!!! The images are what my desktop shows after i press play, and then it will run that cmd window and then close and the play button will set back to normal. The game wont launch at all, I'm essentially on a fresh install of windows, I just reset my drives and now its not working....

Dedicated Server: No mods were found in: "/home/terrariaserver/Mods"

I just updated my server to the latest version (2025.6.3.0) and can't seem to get the mods to be found (this was all working previously). 1) I've got my "install.txt" and "enabled.json" setup in the "Mods" directory. 2) When I run "manage-tModLoaderServer.sh install-mods", it does download the mods from my "install.txt" list into "/home/terrariaserver/steamapps/workshop/content/1281930/" 3) When I start the server via "manage-tModLoaderServer.sh start" and use the "m" command to list mods, it doesn't detect them....

Unable to join server. Not sure which mod is at fault.

I'm getting "the server expects player.max buffs of 0" after the update today, and I can't figure out which mod is causing it, so idk how to fix it. Any ideas? Mod list in the thread....

I have update v2025.5.3.0 and my friend has update v2025.6.3.0, and I cannot download his version.

On Steam, it doesn't say that I can update the game, but when we want to play together, it clearly says that we don't have the same version of the game. How can I update my game? 🙏...

Multiplayer not working

I'm trying to join someone in tModLoader after the update but it doesn't say "join game" at all anymore. Same thing with other friends, even tried disabling all mods and didn't work. Why?

How to handle multiple installed instances

I want to downpatch to v2025.05.3.0. The installation guide says to extract the zip in a tModLoader folder next to my Terraria local files, but I already have a tModLoader folder. Should I replace it, replace its content, create a second folder, or something else? I want to be able to easily return to the current patch once a particular mod is updated. I'm on steam, here's my current folder setup if that helps (I am playing through steam)

Auto Update Mods for TML linux server

Hello, I'm looking for a way to update the mods on my TML server. Is there a script that will fetch the mods from the workshop with API or other to automatically update the mods? It's always very annoying to constantly update my server. The updates are too frequent and when you have a serv with 30 mods it really becomes a daily task updating everything

QOL mod randomly stopped working

Earlier one of my mods randomly stopped working and I got the error in the picture. I exited and reloaded the game to try and fix it but that didn't work. To play I had to skip loading at the start then force reload in the mod manager. Idk if it was part of the mod but now in game I can't access my buff menu to toggle buffs and my tesla potions no longer work, but seemingly other than that the game works fine. Is there anything I can do on my end to fix this?

Download All Button Not Working

When I show my modpack's contents in the mod browser, and click the download all button, nothing happens. I am using a 4500+ mod modpack to transfer my mods to friends' computers (the pack is NOT for loading, only for downloading the mods), and I just tried to use it, but the game didn't even freeze like it was doing something, it just didn't do jack, and literally just acted like I didn't click the button. I WAS using Steam collections to transfer my 5000 subs, UNTIL Steam decided to murder one of my damn collections when I tried to make a new one, since the rest were mostly full. Annoyingly, Steam HATES it when you have large amounts of mods subscribed, despite games like Garry's Mod and Tabletop Simulator having thousands of subscriptions for INDIVIDUAL PEOPLE, so when I try to add my subscriptions to a collection, and have over 1000, so try to make 2 collections by unsubbing from the first collection's contents, THEN adding my remaining subs to ANOTHER collection, the FIRST collection gets erased as soon as I unsub from all of its contents, which is stupid....

I deleted the overhaul mod yet tmodloader is still laggy for me occasionally idk why

I have most calamity mod addons on but not all of them Here all the mods I have on rn What should I get rid of (I can’t get rid of catalyst, infernum, entropy, spirit, or macrocosm due to the fact that I already made the world)...

tModLoader constantly crashing.

I play pretty heavily modded, however I haven't encountered any major issues until now. The game seems to just randomly crash with no error message whenever it feels like it, whether when loading mods after startup, or a few minutes after playing in a world. Due to the lack of error messages I have no idea whats causing this as I have used these exact mods in the past with no errors. :tragedy:

UI Scale messing with Wormhold Potion Teleporting In Multiplayer

My friends have higher resolutions monitors which forces them to use the UI scaling to see their menus. We've discovered on the new TMOD update that they can't use the wormhole potions if they hover directly over a party member's icon on the fullscreen menu map. We've tested in the base terraria version and their scaling doesn't seem to mess with the alignment of the "Free teleport" option in the fullscreen menu. Please see attached screenshots for reference....
