[BUG?]Mapping w/ Multiple tilesets

[Nean]

Okay, so I took two screenshots to show what I mean, because I don't know how well I'll be able to explain this. I have the first tileset, and then I fill the whole map with grass, all is well. Than I click over, to go to the next tile sheet, and then all the grass tiles, switch to the first tile of the second tilesheet instead.




So, in short: You can only map with one tileset per map....
