[BUG] Exception invoking Unity.Tiny.UTEntityGroup:OnOpenAsset(int,int)

One of my projects is broken after creating copies of the same entities from one entity group to another entity groups. After the error, the project loads default unity with normal components attached to it with a tiny entity component attached to it.

Exception thrown while invoking [OnOpenAssetAttribute] method 'Unity.Tiny.UTEntityGroup:OnOpenAsset (int,int)' : NullReferenceException: Object reference not set to an instance of an object
