I'm not sure if it was a visual glitch or an actual feature:
During summer, I was in the savannah biome at night, during a frog rain among beefalos. We lighted a firepit and, when the light was low, we [both] saw a strange shadow fly by our firepit. I have no idea of what it was and whether it was a bug, but I'm thinking it might be something related to A New Reign.
(happened too fast, wasn't able to get a screenshot. didn't find it afterwards)
Anyone else experience this?
