Thanks, I'll take a look at them when I have time.

Regarding this:

We have no idea how one vehicle could cause problems with the LODs of other vehicles - if anyone finds out what root cause is, please let us know!

That sounds very much like the texture problems I'm very familiar with. Unity textures must be powers of two in size. Especially LODs because this game puts them in a common texture atlas where one weird-sized LOD can (and eventually will) mess some other LODs, including prefab LODs.

The issue was hard to debug because it very much depends on asset loading order.

Search for "PackTextures" in VehicleManager or any other manager to see where this happens.

Yup, that seems to be the cause.

Also, it seems it's somehow possible to add non-growable buildings to district styles which results in a game-breaking district style. The in-game symptoms are that growable buildings (and even vehicles?!) stop spawning.

Apparently this district style contains a unique building (not growable):

Would it be possible to (optionally?) automatically prune non-growables from district styles?

Apparently this asset gives "index out of range" exception (weird, considering it's an interchange asset):

This asset seems to cause some issues: https://steamcommunity.com/sharedfiles/filedetails/?id=1807774545

This asset, not broken (as far as I can tell) is being classified as a "Building" in the assets report

https://steamcommunity.com/sharedfiles/filedetails/?id=1580457997

It should ideally be in "Nets" section?

Reasoning: I'm using LSM asset report to determine which nets and stations to subscribe when testing save games from TM:PE bug reports. It saves a lot of time compared to subbing often thousands of buildings/props; for most testing purposes all I need are the networks and stations (other stuff can be subed via savegame later in the testing process if required).

Another broken asset :)

There aren't many assets with that kind of error (weird Building AI due to some ancient mod) but it would be useful if such things could be in the broken assets report with a corresponding guide. There's maybe one or two more instances of that error linked from the Broken Buildings list I posted in OP.

In particular, with broken AIs, they can sometimes be fixed (by asset creator) with V10DeleteAI mod (see this guide[forum.paradoxplaza.com]).

This is probably the most horribly broken asset I've ever encountered in a log file:

Gas Station indeed takes the crown. It is so broken that I wonder how that is possible. Should take a closer look at some point.

@aubergine18, you and I seem to have that addiction to assets you talk about in one of your posts, glad this mod helps with that as well.
