My latest edits to this template should have fixed problems with redlinks occurring on "user-talk subpages" of the kind created by the Flow talk page manager bot (and any others that users or bots may create in the future). The only redlinks this template should now be creating is when the user doesn't actually have a user page, which I assume is the desired behavior.
BTW, why are we linking to the same page 3 times in a row? I have resisted the urge to change this, since I don't read Goan Konkani, so I don't know exactly what the template is saying.
(Note that I am also working on fixing "hardcoded" redlinks created on those subpages by the same bot, but that is a separate issue.)
