Movement squares and arrow disaper

[Seeker]

HI.

in local match game mode.
After a seemingly random number of turns, the blue movement squares and the arrow disapers. i can still move the characters around but not see the avaivable spaces.

at first i thourght i hit a hotkey, bout could not find the right key to get the squares back.
then i found out that i could easiely recreate this bug by ending turn, either with a mouse click or (shift - e) a number of times.
