Demonstration

For most of these this is probably an attempt to replicate the creative motor's hitbox, although these machines are way too big for that to work.

Side Effect

The side effect of this is that connectors from C&A don't work as they require a full block-face to be placed down.
(the front of the converter is a valid spot, but it only sends power on its sides)

Sorry for the giant images, I don't know how to shrink them.

Originally during the development the hitboxes were solid, however because in some cases you need to look at a generator hidden by a converter I decided to make it not a full block (And also possibly because of lighting issues).

I have already known that there is an issue with C&A wires but I don't think it is to do with them needing a full face, I would in general recommend either using wires from another mod like IE or place an accumulator* next to the converter and then take energy from the accumulator.

I will consider working on this more, thank you for the report.

* Not sure if it is called accumulator.
