Scene editor constant crashes on map testing

[GroomoftheStool]

I'm trying to make scene for bannerlord, and my latest problem is that I get this error code when i try to test map as mounted player:

C:\Develop\MB3\Source\Engine\Rlg\rglgraphics_command_list_d3dllcpp:486

I've learned to move the scnobj of my map into the first map available in custom game, but it crashes there as well.
Now this error seems to occur any time i add objects (battanian walls in particular.) I can run the map when it's just terrain and there are no objects.
I just reinstalled bannerlord and the bannerlord workshop, and still doesn't work.
