Civ KOTH sell buff - does not show in /shop

The sell prices displayed in /shop do not change when the buff is active. If you sell the items, the buff DOES apply, but it only shows the correct price in chat after you sell. This means that if you join the server and want to check if the buff is active, you have to sell a single item and pay attention to it's sell price. not sure if this is easily/quickly fixable (I don't know if the source code for the shop plugin is available etc). If not, one compromise might be a command that tells you if the civ KOTH buff is active. I think this is a known issue, but reporting in case
