Crash Report: https://pastebin.com/tVPnkPtQ

I Shot a Wilden Hunter from Ars Nouveau with a Revolver using High explosive cartridges. This happens every time. Curiously, when the crash above happened, the game continued to run for 3-5 seconds after the shot was fired, then froze and crashed. This is the first time I've seen this happen out of the 3-4 crashes I've had so far. I was in a sandstone super flat world (my creative test world).
