package goes well no problem. after launching game this error apeares.
Is that something you wrote ( ObjectArray ), or is it the marketplace pack?
If it’s the pack, then I’d contact the vendor with this.
If it’s you, then you need to look at the warnings in the message log while using that object. You’ll find the system is already complaining about it there. And it will help you to find out what exactly is causing it.
It seems the engine because more strict recently about out of bounds array indices after packaging.
