i hace had the same

Yeah what should I do??

Same

same.

it happens if you play a 3vs with a player in the last slot or with more than 3 players

Is there the way to fix this ?

Nope, the mowas doesn't allow closing the 4th slot. so if you wish to play with 4 players, select a 4 player or higher map.

a few maps crash when i use valour and unforgotten in skirmish mode with no bots it is mainly the maps with no images a couple examples are ostwind, facility, and frostbite but the ones with images all of those i have played on seem to work fine

edit i just seen the post about the specific maps not working
