Ok. Thanks!!

Did a quick test now, 'Whole map' with a couple of mods too but selected only the Wehrmacht + Sturmtroops against Red Army and his 'Tank faction' (can't remenber name now), and it went just fine. So, it depends on which custom faction you talking. If i remember correctly, IFA3, FOW and Northern Fronts factions should be ok to play with. Watch for custom old factions with bad config and avoid unecessary mods as it may give problems. IFA3 Liberation is a odd modpack and may give erros, even though i didnt tested it. Give another test with the bare minimun requieried.

If other WW2 mods than CUP and IFA3-AIO-Lite are installed will game not load? Have many WW2 mods . Choose Faction, but will stop loading. If i choose NATO and CSLA- no Problems.
