Levequest targets that spawn at the end of a quest don't show up on the map

When you finish the first requirements during a levequest and the final two mobs spawn at the end of the quest, they don't show up on the map or mini-map.

For example, I'm currently completing the levequest Necrologos: Torn Asunder. The first part of the quest has you going around to targets to collect 4 pages.

After you collect the 4, a set of Yarzon mobs spawns. (These are the mobs that do not show up on the mini-map). It's quite irritating because I died and can't find where the mobs were that I was trying to kill.

If this could be changed soon, that would be great. Thanks.
