Derius

At the end of Act 1 I had an empty space to hire a praetorian. I rerolled a bunch of times until I saw just the guy I needed. I tried to hire him, but the game would hire a random praetorian that I had fired before. I tried many times but I just couldn't hire a new guy even though the option was here. Now in Act 2 the garrison looks like this. I can't see anything from the second column and if I try to hire that Triarius with <Missing string> it's going to hire the Princeps on the top right.
