Missing vehicle triangle for some routes

[kudlav]

Hi, I've noticed that vehicles on some routes are missing their triangle on the map. There is just the line number.

There should be some fallback when decoding the colour failed. I'd expect always some triangle. It's hard to spot the vehicle otherwise.

The colour in the detail is also wrong but there is at least some.

Also notice the HUGE top toolbar.

And the last, Please add an openstreetmap attribution when using the default tiles from the osm.org.
