W 11.834 Raiders can drop into 'Overhead Mountain' tiles

Raiders can drop inside fully enclosed 'Overhead Mountain' tiles, thanks.

This has been reported, it turned out that the tiles were "thin rock". You need to mouse over them to check the thickness. Just because they're in the middle of the mountain doesn't mean they're thick.

If it is indeed thin rock please re-post with a savegame, thanks.
