I am trying to make a dungeon map...quick style, and I created a floor that is using the Stone Grey Tile bitmap fill. The tile is a square bitmap tile and it has beveled edges to make it look like one big tile...so I scaled it to 5'x5' and used it as a fill style, expecting it to function as both floor texture and a 5'x5' grid for combat purposes.

Only problem is...its not scaled...it starts out lined up at the upper left edge, but slowly gets out of sync with the actual 5'x5' grid of CC3. How do I get my fill styles to scale properly?

Also...I'm asking that here because I'm at work and have very limited access to the rest of the web...I'm posting this via a super secret proxy I have that lets me get to this site from work.
