Some maps just crash - please help me!

[FusionProject]

Hey everyone,

I love your Mod, but I'm having some problems with playing nations at war, because some maps crash, but always at a different moment...
for example Dalian Plant crashes directly after loading, Wake Island crashes after like two minutes of playing, cat island doesn't crash at all ... does anyone have an idea how to fix this? please help me!

thanks, FP
