The Mutant Cleavers are continuously getting stuck beneath the ground and can't be killed. Today, we got no further than Stage 4 when it happened. Imagine our frustration here: from start to finish, only to have the Incursion end on a note like that.
And yes, I / we tried all the solutions that normally work: shot at the ground, threw grenades (Shrill & Hatchlings). Didn't work today.

Add to the fact the already on-going - yet ignored, horrible stability and rubber-banding enemies, it was a nightmare! No one collided with it on vehicle, either. It just keeps spontaneously happening.

I promised the low EGO players that were there that I'd post this on the forums for them. Please Fix. Not even they deserve to be mistreated like this.
