why map crash?

[Hamasei]

Sometimes when i play with wordbuilder edited maps i have a crash and i dont know why.

This may have several reasons. Maybe you used objects on your map that cause a crash or the map is too big and requires too much resources. But if you could post your log files after that crash, an expert (not me ) could take a look at it to explain the problem.
First try to lower your settings and check if it still crashes.

Must have been the object "ebps\environment\art_ambient\buildings\normandy_urban\plaster_1x2_wdg_01. It causes heavy lags, even if placed in WB. Watch out next time you use it
