I did indeed, my friend ended up finding 3 zombies just in a room by breaking through a locked iron door, there was no way to find them otherwise. No yellow dots appeared until those ones died. Took us 1 hour, to clear the entire POI after we killed everything on the roof. Already had all the loot from the end, took us an hour to find the last 3 zombies to trigger where the rest were. I like the loot and the clear quests but holy hell is it a real pain to find the final stragglers.
the sky scrapers are not what you want to complete. The devs haven't seem to modified them yet to perfectly fit the game as they did with other POIs. They're still fun to get through with SOMEWHAT decent loot. Though don't expect to be able to easily find everything because they're still using the exact same models and what not from previous versions and decided to slap the "tier 5" on it. So zombies can definitely be behind doors labeled "locked" without a defined way to get in unless you break it which goes against the spirit of the designated path system.
If you don't want to continue clearing though the night, why not clear as much and as many zombies as you can during daylight, then backtrack and loot the cleared areas at night? Throw down a chest near the entrance with all the spoils, then carry on the next morning?
Wrong. The skyscrapers already had an overhaul. But as LazMan said they still need another pass now that the exclude-feature is available, And not they alone, as Outlaw_187 said there are lower tier buildings too that have this problem. "Slap "tier 5" on them"? They were tier 5 before quests and quest tiers even existed.
I don't think this is true for any TFP-designed POI. The entrance may not be obvious, or easy, or even nearby, but every room you are meant to explore has an entrance other than a fully-intact locked door. Note that if the door has some previous damage, then it is meant to be bashed in by the player.
