I'm afraid the answer might be no to this question, but figured I'd ask anyway in case I'm missing something.

I've gotten nothing but frustration from the minion zoo lately, including it not even loading when I go to the page. I think it would be better for me to just take out the minions and put them in my gallery or vault for now.

But I don't want to accidentally put more minions in there, like by quick stock. Is there a way to "opt out" of the minion zoo so this doesn't happen? Or do I just need to be extra careful from now on?

Sadly I think there is no way. But I would LOVE to find a way to opt out. Maybe this will have to be a new suggestion? I don't particularly care about the Minion Zoo, and when I have to go as far as not to use the "collection" quick stock because it will automatically put minions in there that I would rather sell on my shop.

I feel ya. I stopped using the collection option a while ago because I didn't want duplicates in my minion zoo, but I do occasionally wonder if I miss some plushies and beanbags that way.

I know has been working on it, but I don't know what kind of progress they've been able to make.

GAs can go to the plushie/beanbag collection landing pages and click on 'move all to collection'. It's a couple of extra clicks but at least you aren't missing plushies and beanbags. I have to do that sometimes to avoid using the collection column in QS too.

Oh, thank you! I didn't know that was an option. :) That'll be faster than clicking each individual plushie/beanbag in my inventory after quests to see if I have it yet or not.
