I'm trying to put a cub I just bought into the Cub Training. I've also been trying to get an Adolesence Male I also had to go on Patrol, as well as another I just bought. But for some reason no cubs show up in the training drop down bar, and when I select and try to send a lion on a patrol it says my lion isn't mine, may be dead or have a mutation that won't allow it. But neither seem to have mutations.

Is this a glitch or am I missing something?
