Bug: Swapping Tame Beast active gems - force to Log in screen

Hi GGG,

Just had a funny thing in town when switching an active tame beast for another tame beast (when in co-op).

When the active Companion: Bane Sappling (level 9), swapped for companion: Alpha primate(level 9), it logged both myself and my buddy out to the login screen, and effectively rolled both our games back a couple of minutes (enough for him to have not used the support gem he had crafted a couple of minutes prior).

I was able to replicate this solo.

This is replicatible.
