In my playthrough of 'the Other Side' at version 1.4.1, I Can't use my allies' ability to attack in the developed game project, and can always try to capture no matter how many allies has aquired.
If you could export your save file and upload it somewhere, I should hopefully be able to figure it out.
Here you go, there's the savefilefiles .catbox .moe/0shzzv .json(The turnstile captcha got an error so I break the link into segments)
Thank you. I was able to reproduce and fix the issue. Your save file should work as is.
