I'm on Mission 6, the event just happened, but now it won't let ANY of my people go through wormholes.

What gives?

I had JumpGates on pretty much every portal to block the enemy from sneak attacking. There was a cut scene involving someone going through a portal, and then everyone in that sector was permanently locked from using them.

I forgot to mark this as a problem again.

I had to cheat out the ass. I can't figure out how to dispose of units that I don't want, so I was basically stuck with a totally useless army clogging up command points.

Through the power of relentless and shameless cheats I was able to complete the level.
Are there ways to salvage units? I could deal with not being able to use a hero unit, but the entire army is kind of infuriatingly crippling.

Do tell me how, that would be a lot more practical than suicide the ones that I don't want. I may not have read the manual thoroughly enough.
