Ohhh, no! And I though all is fine with Pure Maps and I can work a bit on other projects before coming back to it. (which I am still going to do though). Although, I still don't know what goes wrong with this background hang. But we can try to debug it again in the future.

Re estimated time: don't shoot the messenger. Pure Maps is not estimating time itself, but the router is. Where I live, Valhalla via OSM Scout Server estimates time quite well. So, maybe UK times have to be somehow adjusted in Valhalla's side - if its the one you use.
