Works great, indeed, and all from one line of code!

There's just two exceptions I noticed throughout the game in my last playthrough:
1- Doesn't seem to apply when you're boarded by an enemy ship.
2- The sixth party member will usually stand on the table to be eaten with the local delicacy whenever you're in a Cafe (lol).

I'm allowed to let off 1, we assume they're doing something important belowdecks, and the second is mostly just funny.

Works perfectly. Thank you for adding this! With mods, there are a lot of companions I don't want to swap out!

Hahaha omg the picture. Incredible work.
