Mystery Gift Exploit

I noticed that when two people send a mystery gift to each other at the same time. One of them gets an error. Both gifts are still sent however the person who got the error does not lose any RP. Using this two people could essentially get 2 mystery gifts (one each) with only having one person pay.

Note: we were both at my friends house i.e. using the same internet connection. Don't know if that was part of the reason this worked.

kthxbye
