Bug 1: When opening the chest in Jackbunny Plains it loaded outcomes all with their own Leave option, one of which was the chest being empty. Bug 2?: As a breeding slave the impregnation occurs even if you escape on the day.
Thank you for the reports!
I fixed the issue with the chest so that should work as indented now.
The breeding slave issue with getting impregnated on the day you escape was intended to work that way so you don't come away empty handed from the event. If you have other suggestions though I'm open to them.
