Hi OP,
here we have again the problem with the payment.
It could be not because of rounding problems, i paid 1 satoshi more, than needed, to avoid this problem:

Hopefully, the next confirmation is early enough ...

Shit, now my deposit of 0.5053553 (expected payment 0.631694) is expired (because of a error in your script?).
@N9_Ninja: Could you please fix this and send me my money!
Hi Admin, could you please check and fix this issue. I lost a lot of money because of this error :-(
