October 12, 2018 – Not knowing what else to do, I restored the base P3d files by running the 4.3 client/content/decoration installers again. It looks like it helped. This is a little not what I want, but I have a chance to fix it.
For now I have installed this on a client machine and am using the setup files to update it to fix the issue.
However, I want you to know that this will help if you don’t want to install it all.
I’m not too far away to go back and use p3d files
With best wishes for improving the gameplay.
PS: I actually installed the P3d files from this thread:
