 I have a client site with a custom taxonomy that has quite a few terms
 (130). Selecting some terms is suddenly problematic.

 When my client creates a new post and selects a particular term to apply
 in the post editor, two other terms are automagically being selected
 without her interaction. She selects (checks) one term to apply in the
 post editor, and ends up with three.

 Upon investigation, all three terms have IDs that begin with the same two
 digits.

 The term she selects has ID 67. The other terms that are being
 automagically added are terms with IDs 673 and 678. There are no other
 terms in the list whose IDs begin with 67, just these three. I’ve tested
 myself, and if term with ID 673 or term with 678 is selected, no problem,
 only that single term is checked. Check 67, however, and all 3 become
 checked.

 I can’t find a logical solution. I think it may be a bug in WP. I’m just
 awaiting a client response, but I believe this has started happening with
 the most recent WP update.
