In the wreckage of one of the game's crash sites, I found two items that have a white box as their inventory sprite. These two items are called a Battery and a Heat Sink, and after looking at the wiki they are confirmed to not be in the game yet. Apparently they just spawned naturally at the crash site, and should not exist in the game at this time. I am on the general build, so I'm not sure what could have caused this. Should probably get a fix.
