So how long does it generally take to get the zen deposited into your account? Is it usually a matter of minutes, hours, days?

It's usually *gasp* instant! oh the wonders of the interwebs! only in this case, neither PW or UP seem to know how to use it right! (Special Equipment Pack - Self-Targeting Facepalm)

but seriously, there's usually a little "loading-style" bar, accompanied by a message instructing you to wait whilst the transaction is completed. after that, the funds are there... except right now. now they're in limbo somewhere.

I need to convert some zen to dil to help fund my fleet's T2 Embassy upgrade, which costs 1m...
This isn't helping it get done quickly.

Perfect world got back to me - UGC is currently experiencing a delay processing transactions. They assure me the funds are not lost and will show up once the problem is resolved. Here's hoping!

same here took forever to upload it would take code but says invalid would not process it so waited awhile then went through

Yeah, mine worked too - I hope this never happens again! Payday is tomorrow, hope it works then ^_^
