Not really an actual bug, just the physics engine being the physics engine, probably got blasted up there by an Ariral firing at a nearby boar. You can climb up there with a hook and bring it down if you don't want it.
Also, unrelated to the rest of this, but how did you get those clearer item icons?

@Bearsjunior the icons are actually just 64x64 jpegs renamed to ".vimg" stored in the folder " C:\Users\[username]\AppData\Local\VotV\Assets\icons ". I got tired of squinting at the little indistinct grayish blobs the game renders for most items so basically I just screenshotted a bunch of the more commonly used tools in front of a chromakey curtain and made new icons in gimp. Gimme a sec, i'll throw em up on google drive if itch lets us post links to that:
