Forum:SH Archive/Source Verification question?

Recently I was browsing through the ship data and I found that the Corona-class armed frigate infobox didn't include the weapons systems listed in the Galaxy at War book which was listed as a source for the page's information. I added the missing information but Grand Moff Tanner removed the data and sent me a message claiming it was unverified. The information came from an offical source of iinfoormation on the ship class so how is it unverified?
