Post Box /Mailing Bugs Issue

Hi! Good Day Team Mazey Flyff Admins I need help and to report this issue, today I was sending my seaking cloak to my other character since I can't do dual on my laptop due to some lags. So I send it and there is no send success window, just nothing I lost my Seaking Cloak with PVE awake to my Inventory and I didn't receive any. So I tried once again to test the error, I send 1 perin and the result is still the same no send successfully window. just nothing. Need Help for this and to fix this issue, Need My seaking cloak with PVE awake back. Thank you and Have a good day!!! Oh By The Way IGN: KiiroiSenkuo and WitchCrone
