Crash during a ritual encounter in Burial Bog map

When I activated my ritual on the Burial Bog map I crashed after a few seconds of fighting (I was using fire and gas grenades on a Gemling Legionnaire in case that's relevant) and I accidentally closed the pop-up box but I'm pretty sure that it was a one liner for something about directx.

After the ritual crash I thought the altars were bricked, but the game "thought" that I'm still in a ritual, I completed the map normally, then shortly after killing the last rare I got teleported into the first ritual that I crashed in and the altars were "unlocked" once again. The ritual altar's type was "Contaminated" (Waves of Blood pass through the Ritual Site)
