That's not my script's bugs, that's Renpy shitting itself for a reason unknown to me.
It'll take someone who's competent in programming to figure out
Best things to clarify:
- if you've been playing an unofficial version or not (some people play re-packed/unpacked versions, the unpacker might fuck files up) (some people play fan-translated versions, the unpacker-stranslater might fuck files up)
- if you used fast-skip (when you hold CTRL down for a long time) and the game crashed (happens)
- if you can provide the save file just before the crash happens and exact steps to reproduce the crash
I have my personal saves up to back from version 0.5, and they all work on all newer versions (only some variables might be fucked up if I changed their defaults later on).
