it happens without any mods installed

These should be the log files i have noticed this bug in multiplayer arma 3 I forgot to mention this information

Wow I really somehow posted about:blank :D
Should've been this https://feedback.bistudio.com/w/ft_a3_howto/gamecrash/

You have attached a freeze dump, but not a actual crash dump
The freeze dump shows that you dragged a unit and released the left mouse button.
Maybe that's already enough.

Holy crap what have you found there.

      for(int j = 0; j < objects.Size(); ++j) // go through all synced entities
      {
        if(objects[j--]) // if entity is assigned to curator
        {
...
        }
      }

Wtf have you brought me to :D
That code is clearly F'ed, why do we only notice that now

And a extra question. Its trying to disconnect the synced trigger.
But should it even do that, why would assigning a unit to a different group, unsync it from the trigger? Do you think it should?

I left the trigger sync connection there.
Fixed in next profiling branch

I have said it wrong in the first thread the game freezes I counted that as a crash I am not sure on how arma 3 goes with the ungrouping of units but the overall problem was that I had units synced to a trigger which activated them and when I went into zeus whenever i unsynced said units it would just freeze the game doesn't crash it just freezes it only turns off when I press alt + f4 or start clicking into the program then it turns white
