Invisible Snails Bug

[Lynx]

It's repost from Master Quest thread.

For some reason i can't go into this door. Is it bugged?
It is start of Level 2.

UPD: There is no snail in this room, but she should be there. Maybe she staying right before me, and that's a reason why i can't move?

Same happens at lvl 1, i stuck into invisible wall, where snain should be (where we turn lever and drop them down).

How can i fix this bug? I think it's not a Master Quest problem (but who knows). The same bug appears twice in a single playthrough. That snail did nothing, no move, no sound, but i can't move into that square too.

Never had that problem in Master Quest or any other mod. I'd say it's either a corrupt LoG installation or a corrupt mod file.

Huh. Ok, i will redownload everything.

That spot shouldn't have a snail, no idea what's wrong, unlikely a MQ bug

This is the room above the pits? where u fight snails and usely people let them fall down in the pits with the lever on level1.
Then yeah, they fall in that room:)
