I've noticed since 3.0 arrived that when selling commodities that have been salvaged or given as mission reward that things have changed.
Sometimes (it's not every time, and I've not yet worked out a pattern) when selling these items that they show up as having been bought at the Galactic average price, so selling below that counts as a loss against trading profit.
Obviously, we've paid nothing for these and any return should be profit. (and this is sometimes still happening).
Do you think this is a bug that's crept in? It's quite annoying to have to hang onto things until they can be sold at above average price.
Items should not show as having been bought unless they actually were.
