Tmod won't open after command prompt opens and closes

When I open the game it all runs smoothly with the command prompt doing its thing. But after it's done it closes which normally does not happen, then a few seconds later steam shows that I can run the game again. I have tried reinstalling all my mods and the game itself, restarted my pc with no avail, turned off and on my defender and firewall. I can run it on an older version but not the current one. I even updated my drivers too just in case and ran it on admin as well. Also, I believe my game...

World Generation

Is it true that the order you enable the mods is the order the world generation loads the mods? Like if I enabled Calamity first, and then Thorium, the World Generation generates Calamity biomes and structures first and then thoriums biomes and structures? I am doing a heavy modded play through and I just want to know if this concept is true to make sure every structure and biome is generated in the world, or at least from most important to least important....

Character is unplayable

So I'm about 20 hours into my first modded playthrough, with Calamity and some standard QOL mods shown here. I just logged in today. I found myself unable to play as my main character. The name is displayed in gray, as shown, with a message labeled (Unknown Error). It also doesn't show the armor, health, or mana of my player, and I can't play on it. It worked perfect just last night, and I haven't touched my computer or its settings since. Relogging proved ineffective. Any idea as to why this is...

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!

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
