Maybe it helps, idk. I literally did nothing though, I created a lobby, then started it, and POOF it turned into static. It is completely random. I do notice however that when using the "allow mod data update" server cheat, it will happen more frequently. When pressing ctrl+alt+p, it will eventually happen when testing a mod. I discovered this while testing a client side mod (that still works to update client mods, btw) here's that one thread showing what the bug looks like https://forums.uberent.com/threads/massive-graphics-failure.64655/
