Sometimes, Weapon group hotkeys (1-9) registers two input events instead of one -> weapon group will be enabled and immediately disabled. This bug occurs only in beta branch, stable version (1.3.8) is fine. I testet both versions with the same world. reproducing bug: Press one of the weapon hotkeys (1-9) several times. There is a ~20% chance that one input is registered twice. Testet it in singleplayer only.
