title/pic says it all.
do you need my system specs?
I've seen this exact same bug once.
The blue box would appear over the enemy towers but only after we killed the tower.
It seems like that is a placeholder graphic for something on the minimap?
Guess it's not just towers then.
happened to me once, blue box appeared on minimap after tower was killed
same happened to me yesterday, every time someone sent an mapsignal a blue box appeared on the minimap where the signal came, and disappeared when the signal stoped showing.
