For the first thing...I assume I'd have to open up JCS and edit the event?

For the second thing, well, I was too curious and since I was resisting to use cheats for 12 years, I had to give it a go, but I had no idea that such a thing happens, as it obviously doesn't in JJ2.

But nothing's as buggy as Dreempipes, I think I completed that only 4-5 times without getting randomly stuck in places that looked normal.
