Some collision models are missing

The 2nd part of the hawker's alley in Limsa Lominsa Lower Decks is missing their invisible walls, need to figure out why it's not present.

In the .LGB, it only lists ***_flr1.pcb

        "Object": {
          "AssetPath": "bg/ffxiv/sea_s1/twn/common/bgparts/s1t0_iw1_flr1.mdl",
          "CollisionAssetPath": "bg/ffxiv/sea_s1/twn/common/collision/s1t0_iw1_flr1.pcb",
          "CollisionType": 1,
          "AttributeMask": 0,
          "Attribute": 0,
          "CollisionConfig": 0,
          "IsVisible": 0,
          "RenderShadowEnabled": 0,
          "RenderLightShadowEnabled": 0,
          "Padding00": 0,
          "RenderModelClipRange": 0.0
        }

I found out that there are more .pcb with a similar filenames, 2-4. Loading all of them gives the correct and complete collision box there. I'm hesitant to just check if n + 1 exists as there are some files which explicitly do not start at 1 or they have gaps in between the numbers. (bg/ffxiv/sea_s1/twn/common/collision/s1t0_a0_kba2.pcb starts at 2, does not have 3 or 4, but has 5, 6, and 7)
Maybe there's something within the .lgb/.sgb or .pcb that indicates there's a follow-up one?

As a follow-up to the previous post, I figured the best workaround right now is to just implement it and provide a toggle for it.
The good thing is that the missing collision is now present in the 2nd Hawker's alley.

The bad thing is that it also adds definitely not present collision models from my experience of exploring the OOB areas of Lower Decks. This probably affects other maps in some capacity too.

Getting closer to 1:1 with FFXIV's collision models is going to involve some manual work at this point which I'm okay with for now. Eventually I do want to figure out how the game knows to load in the .pcb files that aren't explicitly referenced though.
