Activation groups that are on a non-primary chip and show up in the AG panel, are not activatable in flight from the priamry chip.

The craft has two controls, the capsule and the chip. the chip is edited to have and 11th and 12th activation group. In addition the command chip is set to AG12 for simplistic sake. When controlling the capsule, you can see the 12th activation group in the panel, but you cannot activate it.

There was another issue associated to the sound, but I believe it may be linked to how this works.
