I believe there is a bug with stone mason!

I was in a game with Ad_McD, trying to use my stone mason's ability, but it didn't work! I simply couldn't press the special ability button and heal my building.
It was standing on a soggy-grass terrain next to a foul obelisk that had been enhanced with traitorous foundation, and it was undimmed. If I had wishted to move it I was able to do so, but I didn't want to move it and lose my foul obelisk. Foul termite infestation had enhanced the world, the obelisk was at 3 hp, and an opposing unit with 2 attackpower was undimmed at the obelisk. So the only chance to save the obelisk was with the stonemason, but as I couldn't use the ability I lost the chance of winning that match. Pleas take a look at the stone mason!

My guess would be the mason is only able to repair mountain folk buildings.
