@Vertcetti Be patient please, we know these bugs are annoying but sadly the crashes are not caused by our software. We are waiting for an update for the protection software we use. That will fix all the crashes.
Whenever the game throws an error your game crashes as of now. So try to avoid game errors. For example, don't join a server that is full and ensure your game is up-to-date by always launching Plutonium using the downloaded plutonium.exe file.
We are hoping to get these bugs resolved within the next 1-2 weeks. We hope sooner, but we cannot promise anything as of now.
