Null Key Error when merging two Refference Managers

[funtomata]

Hi,
I'm dealing with an issue that only happens on the build in my game and not in the Unity editor.

We have a persistent scene that loads each level additively. The persistent scene itself has some stuff it needs to save, and so do the scenes we load. So we put a ReferenceManager on the persistent scene and one on each additive scene.

When an additive scene is loaded, the Awake in ES3ReferenceMgrBase is called and from what I understand, it notices there's already a current Reference Manager and tries to merge its references.

However this results in a null reference exception as you can see in our logs

Code: Select all

This error doesn't happen in the Unity Editor, only in the standalone build. What could be causing this?

Hi there,

Are you using the latest version of Easy Save?

If so, please could you make a simple project which replicates this so I can see what is happening at my end.

All the best,
Joel
