This update breaks old save files. Unfortunately no way around for this update but to restart. However, future updates will not have this issue, so do save your new playthrough
Resolved: new build tested and uploaded. You shouldn't run into the same error.
Update: I have found the issue and of course it's just one line of code ;_; Rebuilding and fresh upload soon
I will test this tonight and try to fix this. I'll post another reply soon hopefully, so stay tuned and sorry that you're running into this!
