Can't find all my posts

[RootMeanSqr]

My profile says I have 122 posts, but when I try to find them (to reference in new posts), it only pulls up about 20 results. There seems to be a whole chunk of posts missing from about Apr 2016 - Dec 2016.

Anybody else missing their posts?

At the bottom of the 25 that come up initially, it should say "find older posts" or something like that.
