Army vanished, why?

I'am playing Kollion Helleion and one of my armies disappeared. I had a army in asia minor with 4 generals in it (including faction leader and heir). I suffered many casulties so I wanted to send the army to retrain and leave the generals in asia minor. Once I moved the generals out of the army the army vanished. The generals were still there though. I'm just wondering why that would happen and if the fixes will stop that from happening again ?

No, this is nothing that the fixes will make any difference with. I've never heard of this before though, so I think you've experienced a unique glitch. Perhaps if you reload the game before moving them it won't happen again.
