Thank you for making this mod, I also really dislike space casino. But right now, the mod doesn’t quite accomplish what it’s supposed to:

1) Quality modules in the casting is not how LDS shuffle works. It works by casting LDS out of already legendary plastic. So this mod actually doesn’t affect it at all. The only way to get rid of LDS shuffle is to completely remove LDS casting. You can make the foundry craft the normal LDS recipe instead, to make up for it. That’s actually how it used to work for a long time during the development of Space Age.
2) All asteroid recipes should reject quality modules. Basic crushing specifically, but then advanced should also match for consistency. The reason for this is that asteroid crushing also has a chance to return asteroids, and this chance is increased by asteroid productivity. So with enough tech, space casino becomes possible again just with slightly worse numbers. Actually, at 300% asteroid prod, the chance becomes exactly the same as with reprocessing.

another way is to recycle LDS into itself , but then you need to change fulgora a little bit.
(edit: or add to foundry LDS recipe new item/items)

No way, that would affect normal gameplay wayyy too much. Definitely outside the scope of this mod. I also think LDS casting is neat, but any option other than removing it is simply not reasonable to implement.

D'oh! I managed to mix up allow_quality as in allowing quality modules and forgot what I was actually forbidding.

It looks like I can't just tell factorio to disallow quality versions of the casting LDS recipe, instead I'll have to add a "molten LDS" fluid that is first mixed and then cast in a separate machine.

I was going to categorically forbid quality modules in crushers, but then thought that maybe it was overstepping a little and went with this approach instead. But since I don't seem to be the only one to think about disallowing quality modules in crushers outright, then maybe it isn't as outlandish as I thought.

I'll be posting an updated version soon.

Posted a new version 1.1.0

LDS must first be crafted into molten LDS before casting. This eliminates the possibility of transferring plastic quality directly to LDS. Quality modules can be used normally.
Crushers no longer accept quality modules.
