A couple of mods I have installed, including the popular vBookie have options to add extra information to the user part of postbit. When I enable these however, I see something strange.

For the first post in a thread, the display is fine, but the second and each subsequent post the display shows the value for the user making the post AND the information for each user who has posted on the page of the thread being displayed before them.

Example: I post and it displays me as having 500 vCash.
The next person posts and it shows their balance of 300 vCash AND my balance of 500 vCash.
The third post will show their balance of 1000 vCash AND the 300 AND the 500.
And so it goes on...

It's like the SQL is joining to each user record in a thread, and not just the user in the post.

As it's happens for several different modifications, I'm thinking it's something that sits outside the modifications themselves. I reverted by postbit legacy back to default but it's still happening.

Any clues as to where I should be looking to find why this strange behaviour is happening?
