I noted that under mountains tiles, the two mine cave openings aren't functional; when placed on a map, the map gets stuck on load in game.
There were wrong palette entries or missing files or something like that. But I fixed that. Perhaps you have an older version?
If your version doesn't have roads it is too old. '> If you do have the version with roads I have no idea what's going on because all the set and palette entries are okay now and I tested the two mines and they work.
There's still an edge vertex in the wrong position causing a gap in tile m10_01. I fixed this after I uploaded the last update, so this fix will be in the next update.
