I am using SMF1.07 with the newest release of the shop. I just started using the shop in a live setting.
Several people have noticed that if they have credits then leave the site and come back and make a post their credits restart at 0.00.
It doesn't happen to everyone and not everytime. I thought that it was just me, but then someone else noticed it. When another person was teasing me because I tried to recreate the issue by fully changing computers it proved me a liar(my credits were still there, but hers were gone.
I have only noticed this in admins, but not members yet.
I am about to ask members to watch theirs. I did move where the credits were showing up through display.template.php, but I dont think that would cause a problem.
