"I am the creator of this mod. I have not had time to keep Level Extender updated. If it would be helpful, I can make it open source so that the community can work on it and you guys can stop expecting a 3 year old mod to keep working.
If this is the case, I would need to assign someone full rights on GitHub. Just let me know. "
