Crashing during world creation
Roughly 2/3 of the way during the world generation, I got a main engine crash error.
I had a look through the troubleshooting guide but couldn't find anything that seemed relevant to my issue, I tried searching through the logs for some issues mentioned but found nothing....
Game crashes when making a world
My game keeps crashing whenever I try and make a world, specifically at the granite stage.

Game has noticeable lag when using weapon
I'm noticing when I use my weapons a decent amount of lag is caused even though I don't have access to weapons that create a bunch of projectiles yet. Namely the lag occurs when I use the Storm Saber and Caustic Edge from Calamity even though they shoot only 2 and 1 basic projectiles respectively. However I don't really notice lag when using another weapon such as the Bananarang. What could be causing this and how do I fix it before it becomes a bigger issue?

Wotg issue and help
Opened up tmod loader today and come to find out that WoTG just does not work, and I see that it wasnt built for the current tmod loader v2025.7.3.0 and instead for v2025.5.3.0. So im wondering if its possible to set tmod loader back down to v2025.5.3.0, if there is then it'd be great if it was kept simple. Also should i report this to the WoTG server? (if they have one, i just came here looking for help).

Game crashes at random times.
This has been making the game nearly unplayable because it crashes like every 5-10 minutes, and at the start of my playthrough with the same mods it was never a problem, so I don't know what's happening.
Fargo's calamity DLC mod
Hi, i've been trying to do the masochist with calamity mode on and saw that the bosses were buggy cuz they had features from both mods that overlapped. I did some research and found out this mod, but it says that it does not match the tModLoader version or that is incompatible with some other mods.

Blending Problems
Hello! There's a small section of the world that's completely glitched out and the blocks are unblended and all entities in this area are completely broken. It sucks that it's directly in the middle of our base though. What is causing this? I checked if I had the Nitrate mod but I don't.

Server freeze after indeterminate amount of time.
After running a server through both Steam servers and a non-steam dedicated server, after what feels to be an inconsequential amount of time, the server seems to freeze, (monsters & tiles don't drop their loot/drops. Other players freeze their movement and eventually the players get disconnected into an eternal backing up player file load screen.)
Here is the enabled Modlist and the log for the server.
The log does contain the server log for multiple attempts at running the server. 21:22 is around where I stopped playing and left the server on whilst I went to attend to other things....
Crash on boot
When the LaunchUtils finishes up, it appears the "RE-LOGIC" screen but several shades below the normal one "as if the lights were turned off" (i don't know a proper term to describe it). It does not leave any error or code, but just closes off.
Can someone help me?...
Can't Load into a World
i attempt to load in and i just crashes, referencing a few mods (Thorium, Bombus Apis, and Luminance)
World Creation
When I create a modded world in Tmodloader it always show this bar, like in journey.
Why is this appearing and how can I disable it?...

World running poorly post moon-lord.
Hey there, so my friend has been having his first modded playthrough of Terraria for the first time, the standard calamity mod + myriad QoL mods. He would stream the game to me regularly and it would run perfectly fine with no issues whatsoever, however once he defeated the moonlord without me one night, the next day during the stream, his game would visibly become much rougher, to help visualize, it was like time within the game was slowing down. We've looked for a few solutions like switching...
High FPS Support Crashing my game even AFTER uninstalling????
So I saw this mod "High FPS Support" made by Stellar and it just completely RUINED my tmodloader. When I did enable it, all sprites would be faster, enemy spawn rates tripled and I couldn't play the game for more than a couple of minutes before a crash ensued (not because of spawn rates but because of some other unknown underlying issue). And even after uninstalling I still have the high framerate, spawn rate and the game crashes. It's like I never turned it off. Is there some way to completely...
