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). ---
