So I made the minimum donation and received 10 RP. I traded 5 RP this afternoon for a transparent shield. I do recall having 5 RP afterwards but I just checked 4 hours later and it says I have 0 RP remaining. I don't have any screenshots or anything for proof because I don't expect to be reimbursed. All I wanted was the transparent shield so I'm just letting you know about this issue because I'm sure I won't be the only one experiencing this.
