try this with deep copy instead @marsh holly

[marsh holly]

alr

what is the diff between deep copy and normal?

[past zephyr]

.copy only copies the first layer of the list, but if that list contains reference to other lists, these lists wont be copied.

[marsh holly]

ohhh

makes sense

thanks

[past zephyr]

does this work tho?

[marsh holly]

yes

thanks 🙂

[past zephyr]
