Perhaps remind me after the jam and I'll track it down. I wrote about the confusion in the test comments in one or two games.
Viewing post in Disambiguation fails when object id has numeric suffix
I actually remember now, although I don't think it's to do with this.
It was when Adam was trapped in a disambiguation screen, and because he was typing commands assuming he wasn't in the disambiguation screen, it kept returning "?".
I actually implemented a fix for this, so that every two or three times the prompt was displayed, it would re-ask the question. I thought that was good enough to prompt the user they were still being asked the question.
I didn't redisplay the menu just so it didn't spam the screen, going for a lighter touch, but now I think spamming the screen with question re-iteration and choice list every time, is the lesser of evils.
The other change I made was changing the default prompt in TWO theme mode back to ">" so you could see you were in choice mode by the '?' instead.
