New Error: "Cannot add trace to 'Layer'. Switching to 'top or bottom copper'"

There is a new bug in the editor since a few days. Whenever I start adding traces and try to view all layers again, I get the error displayed in the Title. It is impossible to switch to the silkscreen layer. It is also impossible to have all Layers active. The only solution is to reload the browser window.

Using Mac OS High Sierra and Safari 13.0.1

Also I’ve experienced this. Its annoying.
Bugs everywhere.

Many thanks for your report. We got this issue and will take care of it.
