Abyss inside mirage only spawning 1 pit

Currently abyss in a mirage only typically spawns 1 pit. This is probably because it tries to path outside the mirage, concludes there is no available path and stops at 1 pit and gives a reward. Normally especially with atlas masteries and passive systems you could expect 3 to 4 pits. The replication rate of this is extremely high, most abysses in mirage maps lead to only 1 initial pit.

I'm not sure if this is a bug though or intended behavior. Wouldn't say this is a huge priority fix either and it might be complicated due to examining abyss pathing.
