YES i am aware of the crash! unfortunately, it is not something i caused this time...
there is a software unrelated to YOMIH going around that scrambles network packets to avoid ISP blocks/censorship which also happens to have the unintended effect of crashing lobbies. until i figure out how to fix it, i have added a safeguard that is triggered when this software is detected and prevents users of this software to connect to multiplayer lobbies. credit to Leftie, Script, and Adamiya for the find. hopefully this is an easy fix but i will have to do some testing.
sorry i'm late! the last patch was over a month ago and seemed to be working fine so i took a couple weeks off not expecting people to nuke lobbies with sketchy scripts.
i have also added a safeguard from the current unstable build that might help with crashes.
