Thank you for sharing your findings. I have been experiencing the PHOG pink texture issue for months.
Last week I reinstalled MSFS, as I was getting too many CTD’s. I am in the processs of re-installing my airports. I’ve purchased over 300 now. When I run into issues like this, it is no longer worth the time to troubleshoot which of my 300+ Marketplace addons is causing the issue. I just live with the punishment for having purchased so many scenery addons.
Having purchased so many addons and the fact that I no longer want to invest the hours to identify a problem addon makes me reluctant to seek assistance from any developers. I now remove stuff until MSFS allows me to play with some stability, and I endure the problems until I feel the need to reinstall everything again - about every other SU and WU set of releases.
MSFS does indeed run fairly reliably with addons removed. I will install the Feelthere addons with scrutiny. Again, thank you.
