Do you know of the bug that your transfer is very slow in the construction is everywhere and from 300 km / h on, for example, B 109 km / h. This has only been noticeable since the last official patch, thanks to the speed overlay. It is always the same, as long as the lower rails have a common tunnel. As soon as each rail has a single tunnel, everything is normal at 300 km / h. Can you solve the problem?
I know this bug, but I can't reproduce it. However I know how it may come and I made a solution, but since I don't know how to reproduce it, I can't test to know if my solution works..
