Back in FS22 I had a lot to work by finding the map maker and convince them to let me edit the map with multifruit. Except Rogatki, UMRV, Court Farms and Castelnaud, all refused...
In FS25, OxygenDavid doesn't want to let people use his assets (linseed had to be changed) and I lack now the necessary way to contact them. So, the answer is no. No other map, except Judith Plains and from Giants (working on Zielonka and later will have Hutan Pantai too) will be made by me. Sorry for that.
As for the english, pay attention to what it is done (watch the video with slower speed). Back in FS22 I had to convert the gdms by using a german tutorial that I know no word, so it's more of a trial and error.
