It happened to me once with my main account (this one), but I couldn’t repeat it. My secondary account didn’t show this.
If it keeps happening, please log out on the forum once (Click on the icon in the top right, then on the small “person” symbol to see the logout option):
That should also log you out on GayKinky. Try to come back to the forum the normal way and see if it’s logging you on again. Then check if it’s sticking this time.
Martin, it acts like a bug for me. Most of the time the past week of so (I didn’t go in often for some time beforehand) I can’t get into the Forum from Spiral only Kinky (I don’t use Collared or Cupid much, sorry). Occasionally, it works fine, but doesn’t want to clear notification bubbles.
