I know this bug will be resolved very soon, in about 2 years and 79 months and
8429 weeks but I thought to bring few other things to the attention of admins.
2) I changed the texts on my Shipping Method and added more information, details,...
about taxes or other things.(on the invoice page, the text that appears in front
of "Shipping Method:") This even changed those texts that appears on all invoices
even those that are already paid and completed.
I assume if I change anything in my terms, shipping methods,.. it should not
change for orders already placed.
3) I reserved an item for a user. He submitted a quote including that reserved
item. The quote got autimatically cancelled. We tried this twice. Apparently,
buyer cannot submit a quote for an item that is reserved for him. The only option
is to submit directly an order. (he submitted the quote without that reserved
item and it worked, so we can be sure the problem was that single item)
