Home menu link not working when Append URL extension .html

Header says it all..

I don't get the expected url <domain>/home.html when i activate Append URL extension with .html
All the other pages render correcty, only the home doesn't work, this is rendered as <domain>/.html

So it's also wrong with the sitemap for examle.

Anyone know how to solve this?

Sounds like a legitimate bug, please create an issue for this on the Grav repo: https://github.com/getgrav/grav/issues

Was afraid of that, was out of options..

Made an issue for it #621
Thanks.
