Unlimited levels.. wow!!

Good job patching those glitches!

I've again found some more glitches, but atm I'll just mention the most critical one:
It's hard to tell exactly what happens, but the extended areas doesn't work properly yet. It seems like they save what you have discovered and what you have prospected and rocks, but tiles you have dug reset, and sometimes I think it share the same digged (can I say digged or is there a better word for it?) tiles in the area I just were in etc.. I can also remove the floor by the mine entrance by doing this:
1. Go to a lower area of the mine.
2. Refresh game.
3. Load, and you should start on top of mine with the tiles from the floor you were on when you quit.
Good luck debugging this

Making a system for generating areas that can also save perfectly isn't easy, but the result is awesome when you've made it!
