In game version 1.68(.140.908), I am experiencing semi-consistent client crashes during mission loading on multiplayer servers.
I often experience an instant crash on mission selection when client-hosting a server, and when logged in as admin on a dedicated server. Sometimes this does not occur and the mission iniates flawlessly, but if another player joins the mission in progress they will often crash after selecting a slot in the lobby and starting to load, most commonly around the "receiving mission file" phase.
I have reproduced these crashes along with other players (running Windows 10 x64), with and without the latest performance binary, with and without addons loaded, with and without any launch parameters, on both a client-hosted and a dedicated server, with different missions and mission files & settings (description.ext, init.sqf etc). Along with the report files I have included a sample mission that I have been able to reproduce the crash with.
