OpenRA

I builded billions of heavy tanks (i don't remember what for - i killed the enemy using paradrops and one nuke) and selected them all. When i assigned a group (i always do this), it lagged as hell.
I tried with stable and latest playtest - it is there.

If you don't beilive me - try for yourself.

Thanks for the nice demonstration of how bad this gets.

http://bugs.open-ra.org/issues/876 is the bug ticket for this.
