That depends on the game mode.

For leveling world, doing quests while you leave npplayers grinding on some place with high spawn rate is one good way of leveling world, since killing monsters give world exp and quests give an interesting ammount of world exp.

For the second bug, if you are using NT5, that may be because citizens spawning option is turned on at the mod options.

If not, then it's a rare bug.
