TML Crash Before Start-Up

Have figured out it's a "Failed to activate audio client!" issue. When doing the workaround and replacing files in library I am getting a new crash. I've also attached my most recent crash log... Not sure where to go from here. I thought it might be an issue with my audio interface, but still seeing this same crash after I've completely disabled all other audio devices except a basic pair of earbuds....

Modpack Corrupted

So, mid-playthrough I decided to disable my current mods to create one of my own, however upon coming back to it I found out it's corrupted. Like REALLY bad, can't even open the folder to try and reformat it myself. Is there any way I can retrieve the mod list from my player character and enable the mods that way? Because I REALLY don't want to have to go back and forth between the little notification and the mod list....

Single player with MC not working.

I have recently been having a weird issue. A character that has been my primary since returning to TML has, in the last week, been unable to load into newly created or existing worlds. The primary character I use will not spawn, but I can move them around with the "fly camera" option. New characters load in just fine, and they "spawn". Multiplayer worlds work just fine for me. Disabling and re-enabling mods, verifying the base game and TML files and removing/re-downloading mods has not helped wi...

TModLoader not starting.

Hi I am complete noob with diagonising this kind of thing. TModLoader wont start, all I get is the script opening up and it just closes. Base Terraria works fine. Let me know if there are any files I should attach to this to help with diagnosing why Tmod won't start.

endless connection, connection lost

When connecting to a friend on the server, it connects strangely: it says "server found", then "mod synchronization", and it takes a very long time to load, but then it says "connection lost". I turned off the firewall, but it didn't help

Tmodloader stuck on "Found server" but starts server around 30 minutes later

When I try to host a server it gets stuck on found server for around 15-30 minutes. I have been having this issue for around 4 years and I tried everything and it still doesn't work, I tried hosting a world from terraria not tModloader and it started almost instantly so I tried starting a world in tModloader without any mods and it still did not host. I have tried restarting the game, restarting pc, deleting all mods and reinstalling them, making sure no other services use the port 7777, reinstalling the game, disabling the firewall, opening the server directly from the .bat file. I have no idea what else to do I could not find any post on this issue at all if anyone has a fix please help me....

Resource Pack is not making changes to NPC dialouge and Names

Game crashes on startup.

I'm pretty sure it has nothing to do with the actual installed mods that I have but something else.

Friend is unable to connect to a Dedicated server

It seems my friend is unable to connect to our paid server. In Steam, he is unable to join anyone as the "Join Game" option does not appear. He could join me on my local server that I hosted, but no longer on my paid one. Mods are not the problem. I also can't invite him. ...

Sound popping/bubbling bug

Does anyone know how to fix this sound popping/bubbling bug? It's always there when I'm opening or closing inventory, breaking blocks, placing blocks... It's silent but still noticeable, BUT when underwater it is very noticeable and loud. Does anyone know a fix? I use Razer headphones with a USB Razer sound card. I tried: 1. Switching all USB ports/playing without the sound card. ...

Extreme Lag on Mac

I wouldn't say I have a bad Mac, I got the M4 Pro Max and for some reason I just lag super hard everytime my friend uses the kaleidoscope. I'm on a Thorium playthrough with about 20 mods most are just QOL like alchnpclite or BAM. I just get this insufferable dps drop sometimes down to 20. I really find this flabbergasting due to how I'm lagging on Terraria, since I usually play on my pc which costs 1/3 of this mac. Are there any mods that can help me reduce to get rid of this lag. I'm not playin...

Game crashing after loading world

My game keeps crashing after loading my world, without me even doing anything. Same world has previously crashed in moments where many uncollected items were on the ground, but now it crashes simply after being in the world for a few seconds. No error message, and i can't personally locate anything in the logs, except the RAM usage going up, then the crash
