After many re-dos, re-starts & re-skins, I've finally been able to do a small "Pre-release"/snapshot, whatever you wanna call it. I finally released MK-000.01 of the next update. It will be completely different from the past updates & will rapidly expand over time. But for the MK-000.01I've only added in "Flukeman" And a new biome for them to spawn in. And as per usual you can download this from MCreator's website.
Sorry, i can't help you with mcreator but i learn modding with eclipse and there are less bug.Seriously i hope you will progress in modding by use eclipse or another idle because you can do whatever you want withit.
I hope you will not desesper.
