Thank you so much! I thought I cleaned it up in CM but I guess not. Seems to be the same issue for quiet a lot of things.
As for the spacer, I updated them in CM but that didn't help. Currently getting the following error: "Warning: Required container 'thumbnails' is missing."
This is the one here: JK Spacer 10-3.5-FT (0.5m),<kuid2:122285:4020:12>
Ed covered how to add a thumbnail container (which you need to have for all new and fixed assets sent to the DLS now) but that wouldn't cause an actual error in your own asset. I looked into this and found that a dependency of the JK Spacer is, in turn, missing dependencies that exist on the DLS in TS12, but NOT in TS2010. In English, either something's wrong with the database or it's a bug. I have reported it to Auran. FYI, you would be able to hunt down those missing dependencies via the Black Pages. Unfortunately, the Black Pages and the CMP DLS are two different beasts and are often not in sync with each other.
The other odd thing, in TS12, is that I have content that doesn't work but DON'T show up in Missing Dependencies or content that does show up in Missing Dependencies but have 0 error or warning?
Like Andi06's AJS Invisible Station 6T 3.5 KUID2:122285:3405:3, doesn't come up with any errors but in Surveyor it's red.
Ok, based on what you describe, that usually means there isn't a mesh-table present. One of the big optimizations of TS09/10 and up is that you have to tell Trainz, via the config.txt, exactly what the main item in an asset is by filename; previously, the sim had to "guess", which incurs an ENORMOUS performance penalty.
If you were to open an asset in CCP (Ctrl-Shift-C) and then immediately save it, CCP inserts a mesh-table for most objects. It's pretty reliable. CCP also updates the Trainz-build, which can often cause Trainz to start flagging errors that weren't before, but perhaps this will help.
Now, I downloaded that exact asset into TS12 (latest build, 499xx) and I AM getting a number of errors:
Warning: This asset uses an obsolete trainz-build number. Trainz-build numbers below 2.7 are no longer supported.
Warning: Missing or invalid selection for tag 'category-era' in 'industry'.

Forgetting about the warnings, the errors about attachment points can be tackled in one of two ways. If you REALLY care about the missing passengers on the platform, you can use PEV's AttachmentMaker to manufacture the missing attachment points e.g. a.pass_t6_on_57, a.pass_t6_on_65 and so on, as listen above. Alternatively, you can go into the config.txt file and go to queues and find passengers_on_5 and then delete the line #1, line #11, line #12, line #15, and so on. You just have to renumber the left numbers in sequence, starting from 0 to whatever, otherwise the game will ignore any passenger queues after that. So, you'll delete the entire line 1:
1 "a.pass_t6_on_57"
and renumber the following line as 1 and as well as each following line till you get down to item #11, at which point you'd delete that entire line and continue sequentially numbering.
