Vision hangs when changing existing tag links of an instance of a template

We just upgraded to ignition 8.0.1 and we are now having issues with a template created previously. I can create new instances of the template and then edit those, but if I try to edit the tag links of any of the previously placed instances of the template then the whole program hangs without an error.

Close the designer launcher, if it’s open - that’s an unrelated error (fixed in 8.0.2) that’s masking whatever actual error is being thrown by the templates (which might be a different error that’s also fixed in 8.0.2).

Thank you.
