Ah! Another player reported exactly that today.
It wasn't a bug per se, it was just the AI not having a real reason to stop doing that infinite loop since it was a strong "combo".
With the 0.3.13 update I also included a limiter to tell the AI to chill it with the infinite combos. I also made exhaust cards a bit more expensive in the last patch, but maybe it wasn't enough hahaha.
At any rate, this issue should be solved now c:
