It might be possible the first reply to the thread, that the points are not displayed on the same page. Like they are added, but they are not regotten from the database before they are displayed on the page.
I have created threads at
www.vbplaza.com and replied and the points came through, if anyone is able to replicate this issue with ease, I could easily fix it.
But its like a needle in a haystack if its not replicatable.
