recurring payment - charge again, without user id - create a negative balance

recurring payment and expiring roles - works great,
(thanks!)

the role expires in time,
it charge again successfully, and create the new role to the right person.

but... on the user account, it create a negative balance, even that the right amount was charged successfully.

10/29/2008 08:22:14 - Credit card $72.00 -$72.00 Recurring fee payment. PayPal transaction ID:

(not sure if it clear, but instead of user '70' it appears with no id, just '-'.
it seems that somehow - the recurring fee payment - was done attached to the right order, but without the user id.
