First off, thank you very much for making this post in the first place, it's already been very helpful!
But obviously I have a problem or I wouldn't be replying. I have an issue with a block, particularly the DNA Breeder from ADV. Genetics.
I did what you said and changed the Block ID to nothing but when I opened Minecraft I got a block ID conflict. When I looked into it turns out for some reason the DNA Breeder was automatically given the ID of 1004 which was conflicting with the Scent Burner from Necromancy. As a temporary workaround I've changed the ID of THAT block to 423. Just in case it's helpful I've attached the error log and ID conflict log.
