I have been having this problem for a few days now but for some reason the ground textures at ESSA Arlanda are not showing. So far I have reinstalled Windows 10 and Prepar3D V4.2 to see if the issue would get fixed however I still have this issue. ORBX ObjectFlow 2 is enabled in addons as well. Also, I currently use FTX Global, FTX OpenLC Europe and FTX Vector.
HOW TO FIX:
1. Download the older version of ObjectFlow 2. Click here ---------> Orbx_ObjectFlow_x64.dll
2. Go to "C:\Users\YOUR_NAME\AppData\Local\Orbx\FTXCentral\"
3. Place the new Orbx_ObjectFlow_x64.dll in v22.214.171.124 or whatever version of FTX Central 3 you have.
4. Start Prepar3D and the issue should be fixed!
Here are a few screenshots:
