Recently something weird Happen in my forum with the POst reputation Module...
I have 160 of Rep, when someone clicks on + Gives me 4 Points (So 164 is my rep now) and if someone click again is 165. So, for any strange reason when i'm in 160 always to rep jumps to 164 with no reason...
I don't know if is a problem in my forum or is a general problem...
Hmm, it could be that the reputation fell out of sync and it's showing the updated result. I'll run some tests to see if it's possible to provide custom values for reputation.
The only thing I found was if the reputation became out of sync, then it would jump (as you experienced). As for a wrong number of neutral rep, I'm not entirely sure as every time I test it works normally.
I'm going to be updating these soon so if there are any issues I'll be sure to find them.
I did confirm that it's the reputation going out of sync - but Post Reputation doesn't seem to cause it. For example, in testing, adding multiple reputations for a user doesn't shift it out of sync, so there must be something wrong within MyBB itself.
