Haven't checked further but the search function shows all humankind results as if they were from the endless space forum

and then in the profile feed humankind items look good visually but point to the wrong forum in the same way

I believe I got to the right page from the feed before, so it may only happen on cleared items but have no good way of checking that now

Looks like new post feed items point to the right forum, but followed/upvoted have the erroneous URLs
