Map Oasis overlaping spawning areas

Bug Report ID: #174114678
This instance was very laggy (Network jumps from 50ms to even 50000ms in some moments oposite to stable 27ms in hideout, just portal out) and I've noticed two issues:
1. Replenishing shrine was spawned in Expedition area and was vibrant shaking - short video: https://streamable.com/bzgosr
2. Abyssal was spawned in boss room (Ishtaroth, the Perennial) which makes a fight big afford - low reward.
