So I have been playing HoMM3 Hota HD+ with simultaneous turns with some friends lately and we often run into the same game crashing bug.
Sometimes "what seems like random" when we all end our turns, and then have to play the next turn, one of us does not get to play our turn. All of the heroes have full movement, but they cannot be moved and they show a brown path instead of a green, no buildings in the town can be build, and the turn cannot be ended (which forces us to end the game).

(Btw this is not because simultaneous turns ends, when we are 3 players, 2 of us can still move, but the 3rd person gets "Stuck" and cannot affect anything.)

Have anyone experienced the same bug, or know any solution for it?
