Oasis Map generates unreachable area with monsters (#3,221,708,904)

This isn't super-common (this is the first time I've had this happen in perhaps a few dozen Oasis maps) but it is a gameplay-affecting bug.

It appears that map generation placed both a wall structure & a random tent in a way that it formed a complete impassible barrier.

As a result of this, the final 12 monsters of the map are unreachable by any means (the barrier blocks line of sight as well as all forms of at-range offense) thus making it impossible to kill the remaining monsters. Were the (packs) in that are chosen to have a rare monster, that'd have meant this map was softlocked & incompletable.

Bug Report ID: #3221708904

Reproduction: This is entirely a server-side issue, with map generation. The map mods are visible in the attached screenshot; only elements I feel might be worth noting (e.g, that could've impacted generation) is that this map had no boss (or any icons over it) and also had an ailment ground effect. As I do not know the exact generation process order, I don't know if these had any impact.

Screenshot: Attached is a screenshot showing this anomalous behavior. Visible is the minimap, moved slightly to the left to better show the present area. It clearly shows both the collision barrier, as well as how the map is explored and there is no other way to reach this area. Also shown are the map mods.
