Thanks for flagging this, you were right. Seclusion had stopped you meditating, so all you got was the tiny idle trickle, and that can’t settle a new realm or steady a full level at all. It’s fixed: sealing the door now keeps you meditating, with the term’s cultivation bonus on top. If you’re sealed in right now, you’ll start cultivating again as soon as the update reaches you (reload the page if it doesn’t show up).
