Hoping this can be fixed. Discovered it while manually resizing tokens from medium sized to small (D&D 4e terms). After resizing the tokens are not center aligned in the cell but are instead aligned to the bottom right corner. Using a work around by alt + moving the tokens manually and it's becoming very annoying to do this work around.
Repro steps:
1. Create a map with a square grid.
2. Create a token.
3. Set dimensions of the token from 70 x 70 to 50 x 50.
4. Move token.
5. Token is no longer center aligned, instead aligned to bottom right corner.
