Circuit connections to the new combinators seem to work fine in blueprints (at least in my uses), however connecting a supply depot via circuit and then blueprinting causes the circuit wire to not be included in the blueprint.

Sorry, I don't really have a nice way to fix this

I thought I could use a transport depot reader combinator on a supply depot as a workaround, but it seems to not read the contents. Is that something that's possible as an alternative?

sorry, i didn't read carefully enough, and now can't delete this post on the mod portal.

supply depots don't use the complicated internals but are based on normal chests,
and thus supply depots aren't read by sensors, but can directly be connected by wire like any chest.
