Here's what I have done to get SP1 working without problems: This may be drastic measures, but I have everything backed up off the computer to restore later. I am slowly adding my content back in, just in case, to see if anything new should to arise.
Complete uninstall of all TS12...
reboot...
install only TS12, no add-ons...
reboot...
installed SP1, then reboot...
Quick Database Repair, reboot...
finally Extended Database Repair...
then final reboot. And now, here's results.
Seems to be working. I thought I had problems with Mojave again.
Instead, it seems that it is just more restricted or locked down, as I don't remember there being a unlock feature required for the default built-in routes.
So, I selected edit route for Mojave, resaved as a new name (Mojave SP1 test)
Created a session, SP1 session test, and found that it carried over same properties as built in.
That's where I saw this unlock required to proceed with changes.
So, the original Jointed Rail issue seems to be alleviated. And just so every one is aware, there will be new WARNINGS, which can be safely ignored, that Content Manager 3.7 does extra checking to create these: Warning: Required container 'thumbnails' is missing. (this was there before, the others that follow are new to me)
Warning: The *.texture.txt file is missing for texture resource 'mesh_art/mesh_art_512.texture'.
Warning: The *.texture.txt file is missing for texture resource 'mesh_art/mesh_icon.texture'.
Warning: The *.texture.txt file is missing for texture resource 'mesh_shadow/black.texture'.
Warning: An asset must be specified for tag 'texture-kuid'.
Warning: An asset must be specified for tag 'texture-kuid'. Also, there is this, on a few items: Warning: The texture 'gp40_body/window.tga' is a uniform color.
Warning: The texture 'gp40_shadow/shadowblacktexture.tga' is a uniform color. Again, I would just ignore them, as they are just WARNINGS. There will be something that explains all this coming down the road, I am sure. Hope this helps alleviate some myths and questions.u have any.
all seems fine on my system so far just installed the sp1 .
