Actually, I think that is a tah client bug that is starting to appear now. Many tilesets are returned with 0-byte files (which meant delete blankness entry and real tile file in the old server) In the old server this was never seen as the recursive blankness lookup would go up and return whatever blanknessvalue the parent had.

It does require a look at the tah client and make it return proper blank tiles. If somebody would get to this, I would be very grateful.
