Like the title says, the whole text got gray out (see picture) when using both "noknown" and "known" in one [].

Just to manage expectations, I've not forgotten about this issue, and thanks for the report :)
but since it's not breaking things (besides just looking bad), I probably won't find time to investigate and resolve this anytime soon :/

also addon complains on nodead

the colouring issues should be fixed in next update
