Ore Deposit placement softlocks Blight Encounter (#4046684035)

This was one of the most wild issues I'd ever seen with the collision boxes of Settlers League ore deposits here... Somehow a blight encounter spawned a lane portal directly dead center over a Petrifed Amber tree. Every monster of the lane appeared to spawn there, and be stuck in place. This rendered the encounter unfinishable. While the other lanes finished (and their chests spawned as normal, as can be seen in the screenshot) this left the encounter permanently ongoing.

So as a result, this is a permanent softlock for the encounter.

Bug Report #: 4,046,684,035

Reproduction: Cannot be player reproduced, as this was a server-side map generation issue. For what it's worth, this was a stringy map (Abomination) so this might be more likely to occur in maps like that.

Screenshot: Attached is a screenshot showing the behavior in question. The cursor was over the Amber tree/blight lane portal, and thus we can see the health bar of a monster at the top of the screen, and a highlight over one monster. We can also see the concentration of stacked, stuck monsters identified on the minimap in the corner.
