The golden Lotus Commendation from the Mists of Pandaria Timewalking Vendor displays granting 300 reputation for the faction (with the event buff being up to 450). However this is not the case. It actually granted 2400 reputation for the golden Lotus for some reason.
This resulted in me overbuying a lot of commendations (as I rightfully assumed they would only granted 450, like the order of the cloud serpents), that I cannot refund and support can’t exchange or refund.
