I'm getting some issues reproducing the plugin behavior (since I do not have DotMove), the fix intent was to detect if there is DotMove plugin active and if so, use pixel movement instead of grid movement. But maybe we aren't capturing propertly the plugin activation or there is another issue that I'm not able to reproduce.
Anyway, I will investigate DotMove plugin and figure out how to make it work. Please give me some days and I will reach you again.
