4 Potential Lines!?

Looks like a glitch. I never heard of any version having 4-line potentials, nor did GMS extractions ever show the addition of a new cube or anything leading us to think that they will definitely add a way to add a 4th line.

So yeah. Sources, please.

Of course it's a glitch or a hack. We've already established that much.

The question I'm interested in having answered is if the 4th line of potential on these equips actually work, of if it's just an ornamental thing where these hackers can just show off something that isn't useful.
