Description
Hi, I am playing the gog version of Zork: Grand Inquisitor on version 2.0 and the ability to examine items no longer functions which means the game is unwinnable because you need to examine and combine items. The only way to fix this problem was to reload an earlier save and replay through everything I did to restore functionality to an important mechanic of the game. I can highlight the board and magnifying glass, but the script to pull it up just doesn't work any more. I will upload a save with this issue.

Hi, thanks for the detailed response on the issue, and a workaround that doesn't require restarting the game. I don't remember any specific steps to reproduce the issue to break the save, however, I remember fondly messing around with the double fps option at times saving a bunch when its on and off. I'm not sure if that can break the save or possibly manipulate any script or internal timers.

Thanks for the explanation. I have not encountered this bug during the playthroughs I made during development, so the most likely explanation is an unexpected timing bug from the usage of the double FPS option.
There's not much that can be done here, as this is a rare timing bug with the game scripts themselves, so I'm closing this
I tried your saved game. The problem is that a timer that is supposed to start when closing the magnify screen (06110) is not properly reset, so the magnify screen refuses to open.
I'm not sure how you managed to achieve this, and I have tried opening and closing the magnify screen very quickly, but couldn't replicate the issue. It looks to be a race condition in the game scripts, but I couldn't replicate it and break the timer like this.
You can fix your saved game by opening the console with Control-Alt-D and typing "statevalue 6110 0"
The relevant script which starts the timer is this part in gjiv.scr:
puzzle:06105 { # gjiv_put_item_away_then_go
}
If you can remember how you managed to break the saved game, it would help a lot in debugging the issue. Setting the issue as pending, awaiting further feedback. If no feedback is provided by next weekend, the issue shall be closed, as it hasn't been possible to replicate the problem.
As mentioned, the saved game can be easily fixed, but that fixes the symptom, not the possible underlying issue, which seems to be a race condition in the original game scripts.
