1. My colonist with 17 points in "Animals" received inspiration to tame. In the work tab, I set him to be the only handler so no one would intervene, and in the Wildlife tab, I selected only one megasloth to be tamed. A little while later I checked to see if I had a megasloth, and noticed I didn't. If there are any details I might be leaving out, let me know so I can elaborate further. Below are some screenshots.
FAQ: No, I haven't tested disabling any of the few mods I have installed, nor have I used dev mode to weed out the issue. Just want to document this incase it's a bug.
I am unsure if the inspiration work only with taming wild animals or get used while training animals too.
Do you have a savegame while the pawn still got the inspiration, just check when it goes away.
Inspired a colonist and tamed a megasloth without an issue. Maybe you didn't have appropriate food or the colonist was busy doing other stuff or restricted to a zone?
Colonist was not restricted to any zones, and his work priorities were set up such that he would not be busy with anything other than taming or training. That being said, maybe training interferes with this inspiration? It clearly says that the inspiration will go away when an animal has been tamed or the 8 days run up, but.... Maybe that's wrong? Still can't see why this might have happened.
Also want to point out that he was definitely not busy doing anything else because my third screenshot which I'm sure you missed, says that he interacted with the megasloth too recently to re-try. C'mon.
