So far I was unable to reproduce this. Please, if it happens next time, can you open debug console with CTRL+D and enter commands "goal 67" and then "pos 67" and give us the output?

No problem. It appears to be a rare issue.

comment:3 by tentaclemoose, 5 years ago

I've just run into this bug on latest build (2.1.0git5835-g2287a4f607)

goal 67:
actorGoal(67) = 0

pos 67:
actorSet(67) = 98
actorX(67) = -680.000000
actorY(67) = 0.000000
actorZ(67) = -156.000000
actorFacing(67) = 0

Its preserved in the save, so I attached it.

So it seems that for some reason, the "gun"'s goal is set to 0 (it should not do that in that scene) and the "actor" is teleported at another placeholder set (which is expected when their goal is changed to 0).
There are only a couple of cases that this might happen, and one is more likely to be buggy (CompletedMovementTrack) than the other (OtherAgentExitedThisScene).

i wonder if its the same issue as fish dealer in chapter 5, movement track is not reset before changing the goal

Possible fixes:
https://github.com/scummvm/scummvm/commit/72329773d449e0abe36b4dde45aab3927f0677ea
https://github.com/scummvm/scummvm/commit/9fa862c0f40f5d04ae7c520ae6fdd6797bc79b6a

I am unable to reproduce this on my own. Although I do remember a time that it used to happen to my installation too. The attached save file helps to zero in on what might be going on (probably a missing movement flush) but I was still unable to have the bug happen to me (without loading up the save game).

I believe that the above commits should remove the issue entirely.
