After undertaking a quest at about 2010-11-04 19:45 (mud time), the mud no longer processed my commands while I remained in the room with the questing mob. I just got a new prompt without any of the command's usual outcomes:
You ask a naga about 'quests'.
A naga tells you 'I offer the quest 'pretty_clothes' for 100000 experience points.'
<133hp 139ma 100mv indoors 5:11 am>
ask naga about pretty_clothes
You ask a naga about 'pretty_clothes'.
A naga tells you 'I am going to a wedding at my temple and I don't have anything to wear!'
<133hp 139ma 102mv indoors 5:15 am>
undertake pretty_clothes
A naga tells you 'Can you bring to me something pretty? I need something that I can wear easily and would like it
to have many colors, and ribbons.'

I stilled received any mud messages (mobs casting spells, being hungry, tells, gossips, etc), but my commands had no effect as shown above. Chobbs pushed me out of the room, and my commands once again worked normally. When I re-entered the room, my commands again ceased to work. Disconnecting and reconnecting had no effect. Chobbs also indicated that one other player recently reported this, for a different autoquest.
