Cubic Chunks compatability

[Huggi2015]

Building Gadgets (BG) is fantastic for building large repeating structures.
Cubic Chunks (CC) is fantastic for housing large structures.

Trying both at once could yield excellent results. Currently, BG is "softly" compatible with CC in that it does not cause a crash, and partially functions correctly: Copied structures will paste in both creative and survival mode so long as the structure is pasted within the normal height boundaries of Minecraft.

However if you attempt to paste a copied volume of blocks below Y=0, no blocks will paste. If a structure is pasted such that it partially crosses Y=0, the blocks which fall below 0 will not paste.

Would it be possible to get a fix for this? CC is currently only available for 1.12.2, so I assume versions of BG haven't already fixed this issue. I've tried this with BG version 2.8.4 (most up-to-date for 1.12.2) and 3.2.0b (unsure what this is for).

I'd like to think in my ignorance of coding, that allowing blocks to paste below Y=0 would be a nice easy fix, thus making BG compatible with CC is seemingly simple. Thanks for response in advance!
