I used the Temporal Reprieve talent granted by Temporal Augmentation Robe to teleport to a safe place for 1 turn. While I was there, a temporal hound spawned. Some time later I noticed that I only have two out of three hounds with me, so I deactivated the Temporal Hounds sustain and got below LUA error. When I reactivated the sustain, only two hounds spawned - there was a countdown for the third one, but he never appeared. I used Temporal Reprieve again, but the hound is no longer there. Restarting the game did not help.
I can replicate the LUA error by deactivating the sustain.
