It appears the SDK update has fixed taxiway lights using light rows. The lights will now either be a distance apart or “Snap to Vertices” which puts the taxi light exactly where your red dots are. Great time saver! When using the distance option, the editor view and final view are now the same, with the first taxiway light appearing where you start the light row.
BUT - &^(*@ Now the lights are PURPLE again! They are correctly BLUE at a distance and as you get closer they turn freaking purple… 
Edit: I opened a zendesk ticket for this to at least get it in the pipeline as a regression bug. If anyone does -not- see the purple, please post graphics settings.
