So I've been playing the game and enjoying it so far, but sometimes it seems like it just will not spawn hostages or other objectives that you need to complete the missions.
For example, on the first mission the sniper just didn't spawn at all, he was nowhere in the entire map, so I had to restart. It really doesn't make me want to play this game knowing that I can do everything properly and still be unable to beat a level because of this bug, and then have to do the whole thing over again.

This forum covers several games. Which game and missions are you talking about?

Swat 3, and it has happened in 2 different missions so far (the first one and the one in the chruch). After I restart the level sometimes it works, but a lot of the time I still cannot complete the missions.

Alright, so I managed to find the hostage in the church mission (behind a secret door) so maybe the bug is only in the first mission, which isn't as big of a problem.

Sometimes hostages and suspects are hiding in wardrobes and other small spaces you wouldn't think to check. Suspects can be particularly tricky when they are unarmed, trying to hide when they are not running towards their stashed weapons.
