Hi, I think I finally found the cause of the "bridge pillar collision" errors, but so far I have not found an easy way to fix it.

The custom trainstationutil sets the edgeType = bridge for elevated tracks (H10 or H15), but this also affects any ground-level tracks because they have the same edgeListNum. The game then tries to create a bridge at ground-level and the core game code gives the ground collision error.

I think the fix is to use different edgeListNum for elevated tracks. I started testing some new code but it's still in progress... It also needs changes in the .con files so it gets messy.


Unrelated to this I found a separate issue. Both this mod and your Invisible Bridge mod have a file named ibv.lua, but they are not the same internally. This is a conflict because one mod is over-riding the other mod, depending on which mod is loaded last. The bridge problems that @yamasemi reported before might be caused by this.

Fixing it probably requires renaming the file in one of the mods, but that can affect existing savegames so it should probably be tested first. My guess is changing the filename in the Invisible Bridge mod might be better, because bridges are much less complicated than stations.
