Storing Items When Breaking the Mob Farm

Storing enhancements, filters, and other upgrades in the mob farm when it’s broken will work as expected.
Unfortunately, storing the mob capture card or mob capture item directly in the farm is limited by technical restrictions in the latest game versions. This is due to constraints on storing complex item metadata within a block's NBT.

Stacking Mob Capture Cards

While mob capture cards could technically be stackable, in practice this is highly challenging. Each mob can carry unique metadata, such as equipment, loot modifiers, or other attributes, which are stored in the capture card.
Items in Minecraft can only stack if they are exactly identical, including all stored metadata. For instance, one zombie card may drop loot while another doesn’t because of differences in these metadata.

Improvements for Capture Card Stacking

I’ll explore filtering unnecessary metadata (e.g., attributes that don’t impact functionality) to make mob capture cards more likely to stack.
However, it’s expected that some cards may still remain unstackable due to differences in loot modifiers or other key data.

Mob Capture Card Storage Binder

Additionally, I working on a Mob Capture Card Storage Binder, which is able to keep all of your cards in a single slot.

Thank you again for highlighting these points. I’ll do my best to strike a balance between usability and the technical limitations of the game!

if possible id love to see the upgrades stackable in the farms pls (even if its just 2 or 4 per type) pls

This might feel a bit overpowered for a vanilla-like playstyle.
However, I plan to introduce additional configuration options in future updates, allowing upgrades to be adjusted for more powerful effects.

sweet cause having the ability to make stronger farms would be so much better

also to clarify i just meant certian upgrades being stackable like speed and luck and rarity if that helps but just like speed 4 luck 3 and rarity 3 (kinda like sharpness for speed looting for luck and fortune for rarity)
