Stars Above items dropping as other items but only in multiplayer

Currently dealing with an issue where Stars Above items drop as other items, but only happening in multiplayer. Seems to work fine when I load the map up on a single player world, but it does what's shown in the video whenever I try it on the server.

"simulating the world is too expensive"

Hello, Me and a group of friends have been playing in a modded world for around 16 hours, and have recently beaten Astrum Aureus, and then when i decided to progress in the wrath of gods mod and entered a house in the underground snow biome, the second i opened the door our tps plummeted and showed a popup saying that "simulating the world is too expensive", we've tried removing our luiafk farms, slimming down our magic storage, and destroying the house that caused the lag, but is still hasen't stopped. List of mods we are using Calamity wrath of gods multiplayer fix Magic storage Absoluteaquarian utilities...

i think i messed up my install for the iaudio workaround, can someone fact check?

im not too sure but i think i inserted it into the wrong tmodloader

tMod unexpectedly exits when (auto-)saving modded world data.

Title. has been happening within the past few days. checking the client.log shows that an Exception occurred upon Saving modded world data. within the past few days that this is happening, it seems to happen randomly? as sometimes it does it within the first save, sometimes after multiple saves. the error mentioned something about Cloud Save, so i disabled tMod's Steam Cloud. didn't work....

tmodloader refuses to load mods on linux

so i've started using linux for around 3 months at this point, i've tried running tml on linux mint and that failed, i thought it'd be only mint, but then i switched to endeavourOS and the game still refuses to load any mods whatsoever. specifically the "Configuring: <modname>" the MOMENT it reaches calamity which's the first big mod the game literally just crashes. i don't know what's going wrong either. i don't have proton enabled, i tried using it as well. both instances failed. i tried verifying the integrity of my files, but then when i launched the game the issue still persisted this issue is obviously not apparent in vanilla terraria logs: https://discord.com/channels/103110554649894912/1387412620453220432/1387415383455170751...

TML's fps drops severely 2 seconds after tabbing back in, but seems to be fine when not tabbed in

I have a high end pc which i bought a few months ago, and previously have not had any issues with tmod. I went to start another modded world with my friend however I am all of a sudden having significant fps issues, and have not been able to get more than 30fps, occasionally dropping to single digit numbers. I've tried going into my AMD software and set priorities in task manager but nothing seems to work. I disabled all my mods and reinstalled the game as well.

Main Engine Crash

Every time i startup the game it crashes and gives me this error, I will post logs

WorldGen freezes

World generation just freezes on step [R]Piles. Pretty sure someone already knows reason, but I couldn't find it.

Stuck at 4-8% tile loading in multiplayer

I’ve been having problems with loading into a multiplayer world with my friends and it would get stuck at 4 or 8% tile loading data for the past few days. It got to the point where I had uninstalled tMod and attempted to reinstall however it told me the content file was locked. I tried various solutions and had to delete steam and reinstall it for tMod to let me load in for that one session. I tried loading in today and it still wouldn’t work so cut to the chase I delete steam again and reinstal...
