Cursed Ground often doesn't function

Curses with Cursed Ground Support often doesn't work, despite mana always being spent and not being stunned. It seems like it has to do with terrain, as it seems to function fine in wide-open areas.

Im adding to this.

Curses often fail to apply when using cursed ground. Usually its if there isn't enough room for the curse or the player is in the way. Mana is still spent however.

So you end up low on mana after casting curse several times and still no curse is applied to the ground.

I am experiencing this as well. Tight spaces are terrible if you rely on cursed ground. It eats away mana but never curses the ground. It's especially bad in Rituals.
