[SOLVED] A strange issue with my slabs mod

[TumeniNodes]

On 2 occasions now, I have attempted to remove the bottom slabs from my stackslabs mod, because the top slabs work fine with the slabs provided by the stairs mod.
But each time I remove all text related to the bottom slabs, the mod loads fine, is enabled, yet it disappears..., no items in inventory, anywhere?
I cannot figure it out, it seems to be a very odd issue. All I can figure is that maybe the bottom and top slabs are somehow spiritually linked?:P I can provide the NBE files if anyone thinks that might help to take a look at.
I would really appreciate some help to figure this out. I think it is senseless to have extra code in use when one part of this mod works fine with the existing slabs from the stairs mod. I can also provide the original code if needed to compare.
Here is the code with only the top slabs

At first glance, it looks like you are defining the registration function twice. The first definition does what you want it to, the second definition defines the function as nothing. Since the function is ultimately defined as doing nothing then that is what will happen. Could be wrong though as I am looking at this on my phone.

That's interesting, as when I add all of the lines for the bottom slabs back in, it works fine using the 2 function calls.
I will try removing the second function call and see what happens.
Thanks for the observation.

Just tested it and that's the problem. There is another issue though... Place a normal slab, place a top-slab, now place something on top of that.

Cool, thanks! I had not had time to make the changes yet.
Haha, that's not an issue..., it's a feature :P These "top slabs" are just meant to be able to sit atop existing slabs, but not to stack any more than that. Although, if you use the screwdriver and turn those two slabs on their sides, you can place another node, full or slab atop them. I have a pic of that in the original post

I am not opposed to anyone <subliminal hint> who may be able to figure out how to get multiple slabs stacked atop one another, adding those changes..., in fact I'm sure there are many users who would love to see that ability :D
