Last night, I tried to see a particular tog's portfolio, by typing their username in the top search box. Sure enough, Contributor:
namexxx auto appeared, and I clicked on it, but instead of taking me to their port, it split into keywords Contributor and namexxx and of course I got no results. Tried again with four others, and the only portfolio I could get into that way was my own.
After reading the above I tried again this morning: I tried five, and the only two that worked were lisegagne and my own, the other two split into keywords rather than opening the portfolio. Here's what happens when I tried Sean's port:

(Actually, that's not what usually happens; usually you get a blank result with "Sorry, no results were found."
For comparison, I was going to post my Contributor: lisegagne search, but this time it has failed with the 'sorry' message and 0 results.
This particular one won't affect me, but it could affect those with a buyer fanbase, like Sean and Lise.
Of course, I'm banned from reporting it, so anyone who finds the same and wishes to report it is welcome to do so.
However, it's not a 'return' to the bugs season. It's just that bug reporting is supposed to be done in the dedicated thread in the Help forum, where they have been multifarious and of various degrees of seriousness- and in fact it seems this particular bug has been around for a few days according to that thread. Pretty serious, though: c40% of thums on one of my regular 'test searches' aren't showing.
