bugs

If I try to order an armour while I have 2 weapons waiting to be purchased it says: 'You already have a unique order placed'.

dont think you can order unique and ordinary stuff at the same time

@Hobo: that's not what he said

What Jans said.

Whatever, potato potarto,

I made a note to look into this, thanks.

This is working as intended.

Arrived but uncollected orders count for the same as unarrived orders, meaning the two weapons have to be purchased before a unique armor can be ordered.

No the ordering is fine. The "bug" was the fact that it mentions that I have already ordered another unique item. The weapons are not unique ;)
I should have been more clear.

Oh right, that doesn't make sense...

Okay, the error message should be a bit more clear now:

"You cannot place a unique order with other orders still pending."

Lol, wasn't just me =)
