Elise's spiderlings act like regular unit
Sometimes they get treated partially as a purchasable unit. They will take up space either on the battlefield or on the bench.
Units can be planted automatically(when time runs out) but not manually. It's really infuriating. You can actually put the spiderling on the bench by swapping it with another unit, and then the game will give you one extra unit in play, but it's the one on the left and you can't control where it goes. Also can't move units around anywhere because are overloaded on units on the battlefield.
I don't know how to reproduce this bug.
Also, the spiderling has an enemy health bar when on the battlefield but is still treated as one of your units.
I've run into a lot of bugs in this game, but nothing comes anywhere close to as frustrating as this Elise spiderling bug did. I even had a unit deleted from the game for an entire round(nothing particularly weird about it, a unit was put into play from bench and then the unit that was deleted reappeared on the bench the next round).
