Okay so apparently, you can dismember and behead with jellyfish? Will test other obscure forms of damage.

That would have to be electric damage, I'll see if I can check if it is a jellyfish doing the damage

i cant open rain world

Try verifying your game files

how do i do that

right click on Rain World in your Library and click "Properties" that should open up another window in which you should press "Installed Files" and then "Verify integrity of game files"
It might take some time to verify the files and after it is done all the mods will be disabled and damaged files will be replaced.

pairing this with Emerald's Tweaks causes the game to fail to load rip

Can you send the exception log?

Issues found while loading mods!
Disabling problematic mods, the game will now restart.

Emerald's Tweaks & Features: InvalidProgramException: Invalid IL code in DMD<DawSprites>?1762267392:_LizardGraphics::DrawSprites
(LizardGrpahics,RoomCamera/SpriteLeaser,RoomCamera,single,UnityEngine.Vector2): IL_12f6: stolc.s 10

Here is what I got from trying to load Emerald's Tweaks & Features with this mod

( could just be a coincidence BUT ) this mod breaks alot of other mods, causing them to just not work entirely, making mod-cats not appear, the DMS " get fancy " tab not showing up, SB camera roll not working, etc. Not game-breaking but rather confusing

that does seem rather confusing, can you send the exception file?

My game froze when trying to enter a room full of lizards (Including the modded Drone Lizards, if that matters). This is what I think might be related.

My game froze again when entering a room, though in this case the menu didn't freeze.

Received a NullReferenceException about spear lodging, but also:
