I have found a bug. This one happened to me after I sold a Wolfgirl for 150g and then caught a Foxgirl. The first day of training and feeding happened normally as well as the bucket and the collection of pee. After this, the next 3 days and counting won't let me feed her or pick up the pee and the game tells me in each one that I've already done that today despite the fact that I've gone to another day and my energy has recharged to 100
