When using the Builder with a Spatial Chamber that contains a build in which redstone is used, the Builder will not be able to replicate the design. The Space Chamber Card does indicate the need for redstone but the Builder is unable to place it.
Would it be possible to make it so it can?

Aww derp, doing an automation of Compact Machine using RfTools builder to copy the exact needed construction to insert into the compacter area. Could not understand why the redstone did not copy over.
Ironblock with Redstone on top is not able to Copy, but Move from the Space Chamber works all fine.

Bump because automating compact machines needs something like this.

Did something change? I've managed to make the builder place redstone in copy mode this time.

Yes, at some point, I changed which square the builder tries to place non-full blocks in to fix a very similar bug. I'll consider this one fixed too then.

Thanks.
