I've had this happen a couple of times now. There are these groups of champions running around, three or four of them. I approach one and it tells me it'll cost me something like 250 to recruit them. I check my money and see that I have 350, so I should end up with 100 afterwards. But instead of 100, I'll have a lot less, in the most extreme case I had -1000 after the recruiting. Is it a bug with the recruiting, or does it actually meant it'll cost me 250 per champion to recruit them ( 250*4=1000 for example)? The latter still doesn't make much sense, usually in those big groups the quality of the champions varies a lot, they're not all worth the same. And even then it should tell how much the entire group will cost me.
