The Badge-stopping bug is in Mission 8 : Louisiana Voodoo.

I use mind control to free Isabelle from the cage, then proceed. When I get to the central island where the chest containing a replenishment of the mind control ability as well as the makeshift plank bridge which leads to the next island is where the problem begins.

If I use mind control on the central island or when crossing the plank bridge, even though I have one or even fully restored mind control the mind control tab is darkened out and it can not be used again. Although it clearly says I have 4/4 mind control.

But it can't be used any longer. It is darkened out as if I have none. Yet I do.

This really puts a hamper on some of the badges. Without mind control I have no choice but to use the water and/or use Isabella's "connect" ability to get across the plank bridge to the next island.

Restarting the mission has no effect. Same results every time.

This is happening after the initial playthrough while replaying missions to collect badges.

EDIT : THIS HAS BEEN SOLVED.

I'd delete this post if GOG had the option to. So hopefully it gets deleted or marked as solved. There was no bug. It was me being a idiot. Isabella did not have enough health to use mind control again because I failed to remember to heal her. So yeah, I'm a moron.
