I've tried to re-create the same conditions to test, but it seems to be working fine, at least during testing. Do you recall what version of the demo you started with? Also, what version are you using right now?
I don't know if you can share files directly on Itch, but if you could share your saves, I'll definitely give them a look. Thanks for helping me with this, though!
I started with 0.1,0, and have downloaded each patch and imported saves properly. I THINK it might be because I hold either CTRL or ENTER to fast forward through the defeat dialog, and I know holding Enter causes animations / cut-scenes to fast forward in the over-world while Ctrl only skips text, but again, this is more guess work without actually recalling when/how it happened.
Current version I'm playing from: 0.1.2
Version the bug was first noticed with: 0.1.1
Rift pack included: Yes (Integrated to the game on 0.1.2)
Save folder shared through Google Drive
I hope this isn't digging too deep into your Dev time, and if you still can't figure out what is causing the bug, then I guess I got a more personal save file/ copy of a otherwise great game.
