RF15-118 Monsters only start spawning when you get close to them

This could just be a visual bug, but monsters only seem to spawn when you get close to them. This could be related to the view range, but once you get within range, the spawn animation plays and the monster appears.

This also happens even when you can already see other monsters of the same type. If you move closer to a specific monster, the spawn animation will play again and it will appear.
