no, when i start a new campaign its fine, just when importing my old campaigntrevor wrote: Is it consistently broken with b52 and not with b50 ? (that is, you've tried it again in both versions?)
do you get the same behavior if you start a new campaign in b52?
i tried to replicate the problem again, making a map in b50 then opening it in b52, it seems the grid size stays right but its offset information is lost so
in b50 the grid size is adjusted to 31 and offset y -28 and x -8
when loaded into b52 the size is still 31 and the offset is at y 0 x 0
the tokens still jump a bit but its only on the first move then they move normally.
hope this is more clear
