I'll take my random guess.
You're using
show
for background images instead of
scene
.
show
adds an image to an existing screen.
scene
replaces the screen with an image.
The difference being that when you've shown 1,000 images using
scene
, only the final one is actually being shown (and therefore tracked). Whereas 1,000x
show
means RenPy would be tracking 1,000 active/current images.
For a better answer, build your game using the RenPy SDK
BUILD
and upload it
somewhere. Doesn't matter if it's not finished or not working. Then upload a save file from the
/save/
folder to the same place. Then post the links here. If you'd rather not post it publicly, send a PM to the people in this thread you trust to know enough to diagnose it. F95 is a pirate site, but we're more of less trustworthy (at least for a completely unfinished game).
That way, we can look for ourselves. No offence, but "my saves don't work" isn't really much to go on. The details matter, and seeing the game AND the saves are likely needed to solve this one (assuming it isn't a problem with your computer).
