@ragnell804 I did some more testing and got mixed results. For example "1939 Pact of Steel Big World " same polygon problem in 2.5. Worked in 2.6 and then afterwards in 2.5 “Arnhem” worked in 2.5
So i don’t know exactly what is happening. I’ll research it some more and make a bug report. For now, use 2.6 to dl and then u can use 2.5 at least thats how its working for me
