Bugfixes:

From WaluigiMasterr's comment:

"hey there, it's me again, I tested the huge update port to 1.20.1 and I gotta say it's pretty bugged. The torn open, and the faceless wanderer when spawned, they instantly become the legged. And the torn open if spawned passive, it won't do nothing, I attacked him and he didn't do nothing, no cutscene, no transformation. The faceless wanderer do looks at you and does the creepy sound, but he transforms into the legged. Also, the climbing mechanic it's broken, cause I saw the grinning flying away when climbed a fence, also the legged climbed a fence and flew away or got stuck into a house. The other ones are really Good, their designs and everything, but the grinning, the legged, the faceless wanderer and the torn open are bugged"

I've hopefully fixed all of the bugs he's said in the comment. HUGE props to him for calling all the bugs out and reassuring ports are working!
