whooo *lets out whistle*

glitches like that suck and are really tricky to get around. sometimes getting other generals into the town with wrench him from the confinds of the game or you could try to alter his profile a little to bring him to the forefront (give him retinue ect.), you could paste together some false alliance with a former enemy, give them right of passage so they attack your general.

any of these may work, (the trick is to get the person in question to preform a deliberate action) but if nothing works then put your plea in with the modders, they can probably just transport him or something never know what those bunch can do, i'm not very good with computers.

thats the best advice i can give. hope it helps.
