Multiplayer lobby freezes when a third joins.

᲼᲼ · 2025-08-06T20:47:27.257Z

Has calamity and WTG and some other QOL mods. Server freezes (cant interact with anything, items dont drop when mined) whenever the third loads in. Third leaving unfreezes temporarily but server is softlocked back to freezing afterwards,

So the errors are all from Calamity mod and some type of cooldown saved incorrectly it seems
