What happened
I've tried to replicate a working TIS-3D contraption with the help of a Create's Schematicannon, and found that the resulting Casings had inert black squares in place of where the modules used to be, which don't react to touch and disappear if the casing is manually given another module.

What's odder, doing the same without a Schematicannon, just by inserting the Create-created (sorry for tautology) schematic into the world in creative mode, resulted in a seemingly perfect replica that even had its internal state intact - i.e. displays still had previous text, execution modules were doing just what they were doing before, etc.

The machine in question is shown on screenshot and basically just copies data from one terminal to the other, 10 symbols at a time, through the execution module attached to a moving arm. I'm working around the bugged rotation for now, but really hope you could make a fix for that soon. Though that's irrelevant to the issue, sorry. ^^'

What I expected to happen
Casings either copied perfectly, or simply looking pristine as if just placed into the world, instead of being corrupted like this.

Additional thought
I'm not sure whether the issue is on Create's side or TIS-3D side; but, given that I've never noticed such issues with Schematicannon with other mods before and that casings themselves behave oddly (black, don't react to touch), it seems obvious that TIS-3D at least missing some checks that should've prevented such behavior, therefore the issue itself might be on its side.

Thank you for your great work!!! <3

Interesting. I'm guessing that this has to do with modules internally being items in the inventory that is the casing. So in creative I'm guessing inventory contents get copied, in non-creative they don't (to avoid item dupe issues, possibly).

The black faces may then stem from copied NBT state which was based on the last inventory state... I'll have to look into it.
