[FIXED] 0.7 Knight Keep crash

It happens during fights or when I'm just scrolling the map
the grids of knight keep when we place it to build, minus the building graphics appear by itself, around the cursor
but i don't have a builder selected, or sometimes nothing selected. so if i Lt click anywhere on the map it crashes the game to desktop

it happened quite often during the Knight campaign 1st mission. and a few times in skirmish. I think it is associated with having a archon in my army on the screen.

now I've learnt to press escape to cancel the build selection. which returns the normal cursor.

This bug annoyed us quite a few times as well, ruined a lot of lan matches. Seems it was caused by a missing custom building related to hero blinking spell - which BTW also causes a crash. Both got fixed in 0.7.1. Topic closed.
