I had 6 prisoners caged and being drained for close to a week with no issues. I took a few days off and then logged in after the latest patch to see all of them were gone. Last night I captured two more prisoners and went to bed. One I had for a couple hours and drained multiple times the other I threw in minutes before logging off. 7 hours later I log in and they are now gone as well. Not sure why this is happening all of a sudden but it's extremely frustrating with how hard 100% blood is to find. I am playing on the usc official #4038 server (pve).
