Scheme did change in the second edition, but the only change was that you make the choice after discarding instead of at start of cleanup. This has no practical consequence. The topdecking is after discarding, now as before.
However, the online behavior you're describing, which of course is not according to the rules, was at least correct for Scheme before. Now it's wrong also for Scheme. I understand it's to make the play expererience smoother, I'm just saying this because it sounded like you said the online behavior had something to do with Scheme changing.
In addition to to Hermit, that kind of chain could also happen with Village Green and Tunnel. (I have no idea how likely it is.)
