It's been like this in several builds i've used,i'm using 9.6.29.427562 now,i've found this the most stable and reliable version so far.I think so many other builds available have been "interfered" with so much they are not reliable at all,ver "404" was a nightmare for me,constantly crashing,forcing app reboot everytime.
I use a self customised dimka skin,but even with standard non modded skins still get the odd glitch,so i don't believe it's a skin issue.
The glitches aren't really a problem for me,just need to check the route overview,if there is an error it is very obvious as can be seen in the screenshots.Just moving the destination,sometimes as little as 200m can remove the error and i get routing as normal and expected.
