Crash occurs when right-clicking a parasite mob to pick it up. Didn't always occur, and it only happened with one parasite entity. I've had it happen before, though. Might be important to note, I've renamed them to Leeches in the name file.

This error also occurred, but the game did not crash. The item was picked up successfully.
