This isn't really a bug, but something weird happened to me as I was on an avian airship. I was on a volcanic world, and a fire storm happened (I didn't hear a huge crash so it wasn't a meteorite). Well as I was trying to trade with an avian merchant, things started falling and getting destroyed. I wasn't paying attention and I started realizing that the avians were saying things like "that's not yours." I was like "wtf?" until I realized things were falling into my inventory. By the time I realized this, the avians guards were already shooting at me. I don't think this was a bug, as I was playing vanilla Starbound (at least the planets and stuff were, I have a list of mods but they're mostly for hair and furniture). I would recommend that you guys remove avian airships from spawning on volcanic worlds if you can, because that was ridiculous.
