SCUMM: Guybrush can randomly be stuck in the catacombs (Monkey 1)

[dwatteau]

ScummVM 2.7.0git1312-g0d3801cb861 on Linux. This has been reported for the Ultimate Talkie Edition of Monkey 1, but it's quite possible that it happens in all Monkey 1 versions.

Original report by Al.DeHyde here:

In the "hell" bit near the end of the the game I've walked into a room that is blocked by some rocks so I can't reach another exit but I also can't go back out of the one I entered by. [...] It happened on a regular playthrough. I was just wandering round enjoying the noses and eyes. Guybrush entered the room from the left (the screen scrolled across) but he couldn't get past those stalagmites or go back the way he came. I reloaded the game and came across that room again (entered from the top) and was able to walk past the rocks and exit to the left that time.

LogicDeLuxe says "Far before the talkie even existed, I heard of people getting trapped in the caverns, but never encountered that for myself. I have no idea what would cause this. Seems a very rare thing".

The problem is that you're completely blocked when this happens, and you need to load a previous save. So, finding a way to prevent this would be nice.

This room is randomly generated (and changes whenever you move to a new screen) so it's hard to reproduce this. I'm attaching Al.DeHyde's save where Guybrush is stuck, and a save of mine in the same room, where Guybrush appeared from the right and thus didn't get stuck.

(Boot param 999 leads you to the catacombs with the navigator's head, too.)

In the same room, but appearing from the right, and thus not being stuck
