[BUG] Variables no longer defined after repeated reloading

[fishghost]

Hey folks —

One of our players is running into a niche issue, where if they repeatedly reload at a choice menu, they'll get error messages claiming certain speakers or variables aren't defined. This can't be true, as to reach the points in the game our player reached they would have had to interact with those variables dozens of times.

Apparently, restarting the game makes the error message go away and the game is able to proceed normally. I've run into similar issues with bugtesting, where if I use the devtools to reload too many times on game launch, I start getting nonsense error messages, which all go away as soon as I restart the game.

Sample error messages below:

Code: Select all

I'm sorry, but an uncaught exception occurred.

While running game code:
  File "game/script.rpy", line 5702, in script
    menu:
KeyError: u'previous_dialogue'

Not sure if there's anything I can do about this on my end, but I at least wanted to share it here in case it's something that can be addressed in future versions of Ren'py.

Can you update Ren'Py. There as an issue that could plausibly have caused this that was fixed around then.
