why can't i buy funds ?.

A bit of a late reply from me but I will take screen shots next time. I do think I had only one army at that point but due to the time that passed now I can not be sure and I make VERY sure now that I load rt from the army base and not the general supplies tab even if I have one army. Plus I dont feel like taking the risk of losing more money just to simulate the mistake and prove either your or my point. But anyways thanks for the reply.
