Oh no problem, I like feedback regardless. On the anal bit: I mean if I did do that, I'd probably JUST do that, so I wouldn't even have to worry about switch-over, but there are ways to do that programatically. But again, it would either be passive or the whole "humping a wall" thing on Mezz's part, which I've always been kinda eh on.
As far as the bug, I'm not sure what you mean by "approached from the left." You can only interact with that space from the top or right side. I...don't know how he could be "frozen while on the LEFT side of the sparkles." That said, freezing when interacting with that spot was a bug earlier, but I thought I had it fixed. Will test in a bit and get back to you.
Edit: Ok, initial sanity check, I'm not reproducing the bug. I can interact with the activation spot fine after gathering the crowd, and the scene starts as it should. Which is somewhat expected: if this was an obvious bug preventing MOST people from finishing the pack I'm sure I would have heard about it earlier. Which means there's something niche that you managed to trigger that broke it. If you have a save that reproduces it reliably, can you toss it up on catbox.moe or something similar and link it? It would have to be TWO files, the numbered .rpgsave and the global.rpgsave just to be safe.
