It happened to me more than once that I want to recruit a group of adventurers. I open the dialog and the leader tells me, they would join for 200 Gildar as I have about 300 left. It somehow seems that these 200 were meant per member of that group and so I end up with - 300 when the group consists of three members. So there are a few things wrong:

1. It should be clearly written how much the whole group will cost

2. I shouldn't be able to recruit them if I don't have the money for all of them (or have a chance to pick which one I want)

3. It should not be possible to have a minus amount of Gildar, except you introduce some loan system with taxes
