    If I understand well, Steven Clontz has fixed the proof in this entry (dating from revision 1 in 2019), following discussion at MO:q/4878507.

    I have added the MO-pointer to the References (here).

    FYI, the current reference in the References section is a slight misattribution.
    https://math.stackexchange.com/questions/4878507 corrects the proof from revision 1 (2019), but the correction was provided in the question itself (“My thoughts” section), not in the reply. The reply was answering a related but different question, namely to give an example of σ\sigma-locally finite base that is not locally finite. That is not directly relevant to the fix here.

    I have changed the link from the MO-comment to its ambient question.

    But please do edit yourself the way you see fit. It’s hard to tell what’s going on. For instance whether you are “Ricky” and want to be credited as such.

    Thanks, will edit myself the next time. And no, I’m not Ricky.
