The bug I think you can find before 0.57p I have reported the bug here for 0.57p and the bug is at the end here. The bugfix from him don`t work when you get an bug report you as producer have to check if you bugfix aso work.or maybe it's some old save? using old saves from bughunt versions or versions with known bugs seems to be a habit around here. always a chance that a save inhabits the pointers to something that used to be buggy, or simply isn't there anymore.
Aso when you release a free version why you have not from the beginning the bugfix the patreon have had before in the free game. So you as free user must report bugs that the patreon before reported to get later the bugfixes that the patreons have had get after reporting the bugs.
