Disclaimers

• I have searched the issue tracker to check if the issue has already been reported.
• My issue happened while using mods.

What happened?

After extracting the sub-file from the game save file and decompressing it using a gz tool, I found that Item.HasBeenInstantiatedOnce does not seem to have been written into the XML.

I checked the source code and found that Item.HasBeenInstantiatedOnce property is private, so it can't be hold on by ISerializableEntity.SerializableProperties
