, this market's page (and my profile page) isn't available when clicking on links in embeds, groups, front page (a portfolio with the same slug is displayed instead). Will this issue be fixed before the end of week (my timezone, see close date)?

You can bet on this question if it shows up on the front page and with the API. I'm not aware of any other method, but there might be some. edit: Another solution is to replace the username part in URL with basically anything, it doesn't matter

I won't be changing my username before this market closes.
