I didn't make a pull request as I honestly don't have much experience with github. I did ask him on his discussion board if he would update the mod, but received no response.
I've been maintaining my own fork for a bit now. Would you like to collaborate? I added some code to support item/entity mismatch, in order to support Hovercrafts.
I'd love to collaborate. I reposted this mod because I feel it's such a great addition to the game, but there are definitely features and compatibility improvements that could be made.
