I fixed it by rehacking it all, I must have messed up somewhere, but for the life of me I can't find where. I even used file compare and there are no differences.....
I noticed you say to raise the power level modifier to make it harder to gain posts, well for some reason mine works the other way....
At 1 it takes 3 posts to get 1% exp on average. (Where I needed to set it btw because of over zealous users

)
Also no matter what I tried I could not get the exp to work with battles only. I have the correct fields put in the battle options. I've tried on my localhost and online several times with 2.2.6 - 2.2.9 and it won't work for me on any of them. I never had a problem with your last version, so I'm kinda stumped.
Anyhow, this is a great hack bitsys. I love it and so do my users.
(yes, I'm one of the idiots with it on a live board).
