- Fixes issue 787. Hacked mulebots can still be loaded with lots of stuff, including unanchored structures, machinery, items and mobs. They however cannot be loaded with screen, hud or effect-type objects. They also cannot be loaded by anything that is not placed on a turf tile to prevent loading things from your inventory, which would cause issues.
