Tell me about it - you'd think someone from CA would know better and the downside of them at least not checking if things like this would conflict.
No the stage doesn't matter - it is just the Karoake machine itself. I have not tried adding a food register to see if they could at least get some food with that - where that came out with WA - well before we had the official tended bars on LN or the Karoake in AP. So you might try that - but I would guess perhaps it is the food itself and apparently certain mixed drinks the Karoake conflicts with.
ETA - There is always a ray of hope with a new EP coming out though - as perhaps they will fix that as I would imagine a resort ep would want these two items working properly as they would be both things I would want in my resort. Hopefully someone mentions this problem to them over on twitter - I can read what they write but when ever I try to post on twitter it just gives me a big hassle, so I stopped trying to use it - but notice if problems are brought up over there with the game the devs seem to notice and we sometimes get fixes for things mentioned on twitter that we never get mentioned here on any of the forums. I have no clue if they know already and just haven't been able to fix it.
I do know a lot of simmers do not seem to know about this as I downloaded a number of bars made for the store worlds that had the bars, karaoke, and pizza ovens. Apparently they did not test them or notice the drink types reduced and no food from the bars.
