I loaded my save in the main branch that I've been playing in experimental the last couple of weeks and have an issue with 8x2 ramps when viewing them from a moderate distance and below. I tried loading the save back in the experimental branch and it worked fine. The following is what I have tried troubleshooting;
-Updated my graphics drive
-Fresh install of early access
-Tried replacing the problem ramps with;
-Remove and rebuild 8x2 ramp - issue remained
-Replace with a 8x2 foundation - new foundation didn't have the problem
-Replace with a 8x4 ramp - new ramp didn't have a problem.
This issue happened anywhere I have a 8x2 ramp, I checked other locations on the map. When I get closer to the ramp it will render. There is no problem viewing from the top.
