opencycle issues

[Mylle]

when using the opencycle map in order to create a bike route I encounter very often a problem in the wense that the "HERE" map blocks the route...
I try to use the F3 bike highway beteween Velten and Herent (part of the Leuven-Brussels F3), and encounter each time this issue. Strange that teh cycle map is using the HERE map basis for calculations. I have had this problem so many times that for me this opencycle map is useless. If you want more examples, let me know

Daniel
