This glitch has gotten rare, but still occurs regardless. When chopping a lot of wood, as all of us Medieval Engineers do, once in a while a branch that separates from the trees as you chop them apart get stuck halfway into the ground. They then start to spaz out violently, the fly at jet speed in a random direction, if your unlucky enough to be in that direction, the branch will insta kill you, or send you to literal jesus if it hits you at the right angle.

Note: ive literally had to goto god mode when chopping trees to stop dying constantly to rogue branches trying to play Russian roulette.
