Cannot deliver imperial cooking after patch few other people have same issue. tried swapping channel didnt work.

Tell me about it...incompetence.

Extended down time for maintanance and they break aspects of the game?

So, you spend 32mil travelling between LOML to do your dailies and get punished for it by flakey code.

Ran into the same problem.  The Calpheon imperial crafting delivery only displayed "Purchase or sale compelte", but no actual sale occured.  The Heidel one worked.

If you attempt to hand it deliveries multiple times....it will eventually accept them.

I literally sat there opening and closing the dialogue box.
