Game freezing issues

I can enter worlds and such, but on my one specific world that I am playing on all my particles, npcs, dropped items, and pets/minions freeze. However once I use a weapon or item in my hotbar or inventory, everything unfreezes for a short amount of time. I have tried enabling and disabling mods that could be the issue but nothing and I have enough ram to run the game without issues.

Crashing on loading world.

Hello! So recently I've been having an issue with my worlds. When I Create the world, its totally fine and as long as I don't close tmodloader I can go in and out of the world without issue. But as soon as I close the game and come back the next day and try to load the world, it crashes every time and causes the entire tmodloader to close. This has been going on for about a month. my client log is below. Thank you!

Scroll of the Stations

I'm trying to get the encyclopedia of everything (LuiAFK) in my calamity playthrough, and am wondering if there is any easier way to get the unlimited war table (5 war tables) than farming the old one's army. I am currently post plantera, pre golem

Cannot launch game due to exception: "Could not find file '...\Terraria\tModLoader\Mods' "

Trying to launch tmod for the first time in a few years and ran into this error on startup. I've already tried verifiying files and reinstalling both terraria and tmod but that didnt fix it or change the error.

Reverting to Previous Mod Version

I wanted to play a mod's specific version but it auto-updated and I can't go back. I can't figure out how to go backwards, the github hasn't been updated in 2 years, there's no separate download option, and the mod loader doesn't allow me to pick the mod version. How do I go back?

These messages pop up every time I try to load my game.

Since the new update these have been popping up everytime I start my game. I cant disable the mods as we were pretty deep into them before it started going crazy

Terraria Calamity: CR crashing game???

I just updated a bunch of mods, and now Community Remix is causing a bunch of issues. I don't want to disable all of my mods just to play with it, and I also don't really want to have to disable the mod itself. Can I get some advice?

Friend unable to join server

I'm hosting a server without Steam, and for some reason my friend is completely unable to join the server. the error logs on his end say that an operation was attempted on a socket that doesn't exist, and also that the target machine actively refused the connection?
