Dev Notes

Hello. Thanks for coming by, I hope you enjoy my game! (I sure did, it’s my first one ever!)
Your feedback is worth gold! Be sure to tell me what you thought & review it, please!!
And check my SS Account if you want to support me! I’ll be posting more goodies regularly!


Pickling Error

If you’re getting the “Pickling Error” crash when saving on Sandbox:

UNINSTALL URM! IT’S NOT COMPATIBLE!

 
I haven’t been able to reproduce this bug with a clean install of the game, whatsoever.

Using the Universal Ren’Py Mod will cause it to happen. This may be because of conflicting screen names in the code of that mod.
Make sure to check if you’re playing the vanilla version before reporting this crash.

I won’t dig through another person’s code to fix a bug I haven’t caused, report to whoever develops URM instead. Sorry.

Also try this fix if it happens even without any mods.
If it persists even after that, we’re on uncharted territory. Inform me so we can try to figure out what’s happening!
