Seen very little mention to the multitude of multiplayer bugs.
No ideology/colonization events on colonizing non-precursor planets
Some precursor planets not providing bonuses e.g. Thulium Moon, no Thulium
Crashes on game initialization and/or starting the game as a different civ than you selected
Desync issue if you end turn and have an idle ship, if you move the idle ship the game hangs in an endless loop, if you pass the game is fine
Some nonmultiplayer bugs
Snathi tech provides +1 to all mines instead of presumably +0.1
