Wolf Pack never respawns/spawns only one w/Last Gasp Support

Title - standing around with one wolf left alive for several minutes and they simply do not revive above 1. I let that one die and it then revived.. as one. Totally broken apparently.

I re-activated the gem to resummon 4 to re-test, but removed Last Gasp, and then they respawned as normal.

Last Gasp ruins the skill basically, very bugged

Confirmed still happening as of 0.4.0b hotfix 5.
