I sent today some xem to poloniex and never arrived\
Have anyone the same problem?

?
Yes, I have exactly the same problem, two days ago I sent (just small, but still) deposit into Poloniex, correct address, correct message, visible in blockchain explorer, everything clean - but it hasn't been displayed processed by Poloniex till now.
I filled trouble ticket (#711319), it's now "Being Processed since 14 hours 37 minutes", nobody answered to me till now.
Mr. Kauppalahti, if you have some "paths & ways " into Poloniex, could I request you for request them ... ? ;-) Many thanks kiitos kiva! :-)
