Shrine locations spawn at map end

There seems to be an issue with shrines tending to spawn almost at the end of a map. I noticed it a number of times by now, that i almost clear the entire map to find a shrine right before the last couple of monster packs. I assume this is neither intend nor desired.

Example screenshot enclosed (map almost fully cleared, 26 monsters remaining including the last rare, with a shrine spawning basically right in front of them)
