Magic storage crafting actually not crafting

When using magic storage crafting in multiplayer, some items just won't be crafted. It uses the stored material but the output never comes out. Anyone had this issue?...

Sudden crashing

Right as it says, the logs are attached. I've done multiple playthroughs with this modpack and am only now experiencing issues. I'm playing using a docked steam deck, which may be relevant....

Multiplayer bugging

I have a world that once loaded in multiplayer it bugs out. Tiles stop existing or they generate sideways and entire sections disappear. In singleplayer however everything works perfectly fine and i dont know why. This has been happening to all my worlds recently I tried changing mods and stuff but to no avail. I need some help

Indefinite Syncing Mods Issue: World Host

Loading screen is stuck on "Syncing Mods", no isues during start-up or during "Starting Server" as far as I can tell. There are three main errors in each of the two .log files in this thread, but I am more inclined to believe the issue can be found in the server.log file. Quick help would be greatly appreciated as a friend and I are planning to play today (5/17/2025).

Need Help

Need Help. Only change that occurred was BetterZoomMod updating to 5.01. Game originally crashed when I would select "singleplayer", but after verifying the game files it was able to launch, but it ran in super slow-motion. Now it crashes when I try to launch it at all. Here are the logs.

Server hung for more than 10 seconds. Cannot determine cause from watchdog thread

This problem didn't happen when me and my friend played a full playthrough before, but all of a sudden it started happening when we started a second playthrough.

.net Host Problem

I have a weird cmd window open all the time while im playing with TModLoader. I read that its for some kind of "LaunchUtils" for Linux, but im playing on windows. How do I get rid of it? ANd when im Playing together in Multiplayer with some Mods, i often get framedrops, could that be the reason for it?

Tmodloader resetting and worlds corrupting

My tmodloader will randomly reset all settings and keybinds, and any players or worlds not saved to cloud will corrupt and become unusable. It seemingly happens randomly and on startup, tmodloader asks me for my language again. I;ve had to reload backups from the previous day multiple times this infernum playthrough due to this which is highly annoying as I have to remake my progress. Does anyone know what is causing this issue?...

Hi, every time I try to enter tmodloader this message appears and I can't enter, I don't know what could have happened since everything was working fine since my last gameplay and I haven't added anything else since.
