Keep losing the :4 (randomly) in declarations

this has happened, enough, that i’m starting to think that it might not be me, but it might be some weird bug, because it only happens in lines that look like this:
var myForm: 4d.form

the :4 gets dropped. before 0.14.3, i wouldn’t get a visual cue in the editor, but at least now, i do

just had another weird one: one of the slashes on a comment line went awol
again, 0.14.3 is better about marking syntax issues, so it was obvious.

and the :4 just went missing in a class i haven’t even opened, in days (weeks?), the datastore class
