I do know that if the map was created using FMB+, and uses objects that FMB+ unlocks (ground plates etc.); then you can't save it with standard FMB.

No... when a new map is "not saving mission file without deleting the line in bldconf.ini"... it happens at the start.... before any change in FMB unlocked or FMB+ unlocked... with a nude map without any object (generic or modded) or any modded texture...

Nobody has found the reason until now... I tried millions of things to understand this bug... but at this time, nobody can't say why some maps are "saving" and some others are not ??????

Sometimes, you get a not saving map and when you try to make it with an other size (ie 100 pixels more in each side) it gives a saving map... Is this related to the size ??? I don't know because I can't get valid rules to transform a not saving map to a saving map by changing size...

Sometimes I thought it was related to differences in treatment of grey colors of map_c between Photoshop and Gimp... or to differences between various map_c tools... but again, I can't get rules...

So at this time it remains an open question... if someone has a real answer, PLS SHARE :wink:
