Hi!

I’ve not dug deep into how the localization system works, so please excuse my ignorance here. Any guidance would be much appreciated…

I’m using the 1.5.3 package in Unity 2022.3.44.

I’m getting a variety of null reference exception errors from the Localization package, specifically JsonSerializerTrackedObject.

These two in ApplyLocale:

And another:

I have not been able to consistently reproduce these errors. If these are user errors, are there any good ways to track down the source of the error?

Many thanks!
