Problems moving PCs on a map with a small grid
There appears to be a bug in the token movement on maps with a small grid (with locked tokens). We have been suffering from this during our play sessions for the last month or so. I turned off all add ons and still had a problem. I finally got time today to do a little experimentation and send a post. Lo-res maps are good when playing across a network.
When the grid is 9x9 or less movements do not complete. They often stop part way or refuse to move at all. A green select-able square is shown at the target position but the player icon ends up in the wrong place on GM and client maps. The issue doesn't appear to manifest on maps with grids or 10x10 or greater. I needed two machines to see the problem (the GM can't really see the issue on their own).
It feels like a rounding error bug in the path the token takes to the destination square. Even when it works the path is a little eccentric (and slow) going along a cardinal direction for a while before homing in on the correct square.
Bresenham described how to implement the algorithm without rounding errors in 1962 so no real excuse. :D
