Hickory: Every store has it's own flags for what it can buy and sell. If it doesn't buy or sell items, it can't identify them.
That makes sense. However, in one of the stores I was able to identify for instance a ring of protection, but the pantaloons and the wand was not possible to select in the Identify tab of the store. Don't think it's been like that in the game before, so I wondered why that was.
Not a big deal of course as I'll have the spell at some point, but I did find it odd.
Makes sense about Tutu vs BGT then. Would be nice to have that feature in BGT too, though, as it can be a pain to relocate people if they are stuck out in the wilderness. Heck, despite knowing on what map Kivan was, I walked hither and tither just trying to find the bloke.
e: Do you mean categories of items above btw? This was in the carnival and Beregost, and iirc they can't sell or buy everything, so perhaps that would be why. Suppose I've tried to identify items in previous playthroughs at stores that deal with everything.
