Yep. I get 3 tip missions and 'investigate' all of them. If any of them are not in the zone I am in I dismiss it. The good news is they drop frequently enough that I can just ignore the ones with inconvenient doors.

If I know I'm only going to be on a limited time, or I'm teaming then I drop or skip them, but it really doesn't bother me much.
City of Heroes was my first MMO, & my favorite computer game.

I could see it justified if they were actually relevant to the zone they gave you, but at least with the villain tips I've seen, notably in the 30-40 range, the flavor text will be all "X event is going on in Y zone", and the zone I'm sent to isn't the one that is actually mentioned. I'd go so far as to guess Tip locations are still fairly buggy, rather than simply an oversight.
Does anyone else get aggravated that tip missions in some cases send you all over to different zones? Here's an example: why do some level 50 villain tip missions send you to Port Oakes? Not only is it a zone that is far below level 50 but you can't even street sweep in PO for more tips once you're done with the mission because it's below level 20. I end up dismissing every single one of these and my morality still ends up guess where, Port Oakes!! One of the main reasons I prefer villain side over hero is because there's not as much running around between missions. This is very annoying to me and I'm wondering if it bothers everyone else as much as it does me.
