That's a bunch of things to try. I have closed & opened the app to no avail. Also, refreshed the browser (Firefox) & cleared the cache. Firefox is up to date, same problem. A map from 2 days ago works great, last night's map has the problem described above.
So I'm thinking;
* Has DD made any changes to its software in the last couple days?
* Has anyone else reported a similar issue?
* I think maybe it needs to be logged as a bug
Anyway, soldiering on, I'm gonna make another map this morning, and will report back to you if the problem persists.
