You may have given someone a key, or it will appear like you have, but you should revoke the keys and rekey them. The keys you do have, should work.
I had 65 keys and lost almost all of them, some of of the ones I gave out didn't work for friends and vice versa.
The chat bug isn't fixed yet, so just shift+enter to quickly resolve things, and instead of reloading, just key an inactive fellow, and unkey him/her.
Hope that helps. Cheers.
tl;dr If your key menu said that it has given out keys after the reset (which probably should've been gone), then remove those keys and rekey the glitches.
P.S. If all goes well with you, then that's awesome.
