Thanks, community! I was really dreading the task of remapping Kristiansand after the redaction bot had been cut loose on the world but this has so far gone a lot faster than expected.
Vågsbygd, Kjos, Voie and Andøya are now in pretty good shape and Jaktodden has actually never looked better as before it was just marked as a residential area without any roads.
115 are done and 30 validated according to the Task Manager (50% done soon) and I expect the last 50% will be a lot easier :)
Big chunks north of Lund, the area around the University of Agder, are still blank though, so there's tracing left to do.
South-east of Varoddbrua, Odderhei and further south are blank and even an entire island has gone missing south of Tømmerstø. It has actually been traced again but updates of the coastline seems very infrequent. Back north of E18 Hånes still needs to be traced.
I think I can verify at least a couple more squares at the OSM Task Manager but I'm turning in for the night.
