1. Yes it will wake up every single night instantly at 20:30 server time

2.. It can be re-knocked out each time to continue taming, the progress WILL stay. This is what the devs made happen with their "fix", making it look like the waking up is a intentional part of the tame and a wanted feature for it by them.

3. When it wakes up everything in inventory gets deleted, you need to take food out before this happens.

4. 3 hour starve tame is the way to go pretty much, no narcotics needed as torpidity goes really slow, just keep knocking out.

Hope this helps <3
