Thanks Tina. Got an alliance thief I'm trying to track down.
Ugh. Probably using a disguise kit too.
Good luck.
Tina, MyUO is probably the best tool for finding a thief stealing from within.
You go through all the names of each guild, to make a master list.
All names that are blatantly not on the NPC/disguise/incognito list on one side, those on that list on the other.
Look for the names that change - or disappear from the "real name" list to be replaced by an NPC name.
I found out who the thief was, the last time my PvM alliance got infiltrated by a minor guild adding someone that was a total fraud, because that person's character was never in MyUO, but there was one name constantly changing from NPC name to NPC name. Since there were only 4 RL people in the guild, we contacted 2 of them and had them switch guilds, then booted the guild from the alliance (the 3rd, who had all the GM/emissaries, had taken a break from the game shortly after adding the criminal, and we had to fill him in on what happened when he came back a couple months later)
