Started the portal, then realised he wasn't grouped (doh), so clicked on him to invite, right-clicked by mistake, but he was standing behind the portal >.< Got to SW and DCd as I landed.
So yep, I took a 2g tip from a poor guy, not in a group, then took my own portal. /facepalm.
So if you're reading this, or anyone has complained to you about an evil, thieving Mage stealing their gold then logging, please send me a mail and I will send his g back. I'm sorry but I can't remember your name :(
