Hi! Really enjoying the map. Found a small technical issue you might want to look at: the log fills up with Error: Blocked area map is wrong size for terrain (2048 x 2048) vs (4096 x 4096) while placing buildings. I noticed it specifically when placing the MA7 (ORVA Poulailler) building, but it may affect other placeables too.
I looked into it a bit: maps/data/masks/BLOCKMASK.png in the map files is 2048x2048, while the terrain is declared as 4096x4096 in map.xml. Resizing that mask to 4096x4096 should fix the mismatch.
Thanks for the great work!
