Well, after getting a set of boss rexes and saddles made, I started to do the Manticore on SE. Did Gamma a few times, Beta once (only took 5 minutes) and started doing Alpha. Did 4 of them just fine then on the 5th one (about an hour ago) boss wouldn't land and the fight timed out. So now wondering if it's even worth it to do this boss since it's clearly still bugged. Maybe it time to focus on Otter breeding lol.
