They should've just put a wall or fix the contact issues. Instead the caused people doing a normal thing to wipe. It's a lazy way to fix something without acknowledging an actual problem
I'm going to go out in a limb and assume the original cheese was possible because of the way the walls had to be coded in order to allow the zamboni to work. But the encounter works 100% fine, minus a few frame rate drops, as is. So the choice is between creating an area around the zamboni you have to stay in and altering the environment and potentially opening a huge can of worms. I think the solution is obvious especially when it will impact 0 people after yesterday.
