Thanks for the test Dinorius! Oddly, I do not appear to have <kuid:-1:101211>, and neither do I see it on the download station, so something is amiss. I do have these, which are version 2.9:
<kuid:-25:992> F7 Interior KPH RHD
<kuid:-25:1005> F7 Interior MPH RHD
My copy of <kuid2:225098:102247:2> WAGR X Class appears to use <kuid:-25:1507> F7 Cabin TRS19 - LHD/KPH when I "List Dependencies (List asset versions shows no other interior version), and yet when I edit config.txt, I do not see that asset listed, only <kuid:-1:101211> !!
SOOOO, I replaced <kuid:-1:101211> in the config file with <kuid:-25:1507>, and voila! It now shows as not missing dependencies! <kuid:-1:101211> is not in the obsolete table for kuid:-25:1507>, but I think we may have cracked the case. If these are referring to an old interior that I do not even have and is not using the one in the dependencies, then a quick change will fix it. My one question is why the config.txt and the dependencies list is different? I always thought "List Dependencies" read the KUID table in the config.txt!!!
EDIT: OK bizarre! I opened in Explorer to look for any scripts in the folder. None there, but then I did a revert to original. It now shows as "Installed from DLS", not missing assets, and yet the reference has gone back to <kuid:-1:101211> in the config.txt file. I think somehow I am now in a parallel dimension somewhere. It may be the Twilight Zone or the Outer Limits.
