Hi there, was noticing a Bug that happened before, but was seemed fixed in an earlier patch just up before beta 4, The game seems to think on strategic level that my mouse is half a tile lower than it actually is (its less bad when I zoom in).
This is terribly hard to screenshot due to my mouse not showing up on screenshots 
But it is really really annoying, so If you need any info just ask and I will do my best.
Sincerely
