quests to buy goods not working

[Mythanwy]

Hi
Tried to complete daily and guild quests today. Both required buying goods, which I did. Neither of the quests registered the purchase and I am unable to complete them.

I think others have had the same problem recently so maybe there is a bug

A little more information would help, what are the name of the quests, what do they ask exactly?
Are you sure both are not waiting quests?

'Waiting' quests are often a source of confusion, has caught me several times
