i dunno if it's a bug, but one thing is making me crazy and i need help:
Every time i try to use black marketer's bulk buyer license it fails (look at the screenshot)

Like you can see (on the screenshot) i have license (60!), few millions of zenny also. I'm not overweighted... i just don't know what's going on with this..
I don't know since when it is not working properly. Few weeks ago I used bulk buyers license hundreds of times and it always worked...
any ideas?
