Getting a new error with when navigating through main windows using our custom built navigation. This just started happening after my latest publish, but I have no idea why.

```auto
Error invoking [TranslatablePanelTitledBorder]PanelTitledBorder.setUntranslatedTitleText(Help Desk)

SerializationException: Error invoking [TranslatablePanelTitledBorder]PanelTitledBorder.setUntranslatedTitleText(Help Desk)
	caused by NoSuchMethodException: com.inductiveautomation.factorypmi.application.components.border.TranslatablePanelTitledBorder.setUntranslatedTitleText(java.lang.String)

Ignition v8.0.12 (b2020042115)
Java: Azul Systems, Inc. 11.0.6

```

I don’t know what if any extension function is causing this I have to suspect it’s something behind the scenes otherwise I would get a line number. Any thoughts?

You’re using 8.0.12, it’s in the error message.

You are right. I have a version mismatch, my development environment is 8.0.14 but my production is 8.0.12. Don’t know how that happened. So upgrading will resolve then this.
