Title says it all - is this the way Bolt of Glory is supposed to work?  Seems bugged to me - perhaps because its deactivation only happens when a paladin types "flee?"
[Edit] Oh and by the way I truncated the log so you could see the relevant parts.  The nimbus remained for about 2 full minutes after the paladin left.
