Getting fighters out of planetary cargo

[Gusset]

I can't seem to reliably get fighters where I want them to be.

Once they are in space, I can move them around a solar system. That isn't a problem.

The problem comes when I'm trying to do a non-combat launch from a carrier or planetary cargo, or transfer them to/from planetary cargo from/to a carrier. The cargo transfer and unit launch menu items have not been performing reliably; once in a while they get into space, but more often than not, my orders seem to be ignored. I have had fighters stuck in cargo holds of planets for many turns...can't launch them into space where they would be able to move to and participate in warp point or planetary defence, and I can't get the things into or out of my carriers either.

Sometimes it appears as if one or two of them do what I want, but the rest of the group does not. The manual says that transfers are limitless (ie you can do infinite transfers in a turn), if I understand it correctly.

This problem is occurring in a simultaneous turn (MP) game.

Any insight? Are there known bugs in the cargo transfer functions, and if so, is there a workaround?
