Ignition failure? Navigation/OverviewNav does not exist

Good evening everyone; I’m having a recurring issue regarding this. I’m an amateur when it comes to this software. Is there any troubleshooting steps I could go through? Possibly edit some files? Any input would be greatly appreciated.

Well, does the tag Navigation/OverviewTag actually exist? If so, where?
What’s trying access it?
For simple navigation everything is just set up in the dialogs.
