When picking up a spawner (rogue or dungeon) it losses it's original data regarding what mob it spawned and the stats it had, leaving an empty spawner in it's place

Yes is fixed now, thanks for the help.

Quick question on a different topic, are rogue spawners implemented?

Try with 0.2.2, it should be fixed now

What mod version are you using? And could you send your mod list?

Mod version is Zenith 0.1.7 - 1.20.1
The mod list of the server running the world:

• Bookshelf-Fabric-1.20.1-20.1.6.jar
• cardinal-components-api-5.2.2.jar
• cloth-config-11.1.106-fabric.jar
• EnchantmentDescriptions-Fabric-1.20.1-17.0.8.jar
• fabric-api-0.90.4+1.20.1.jar
• fabric-carpet-1.20-1.4.112+v230608.jar
• fakerlib-0.0.7.jar
• InventorySorter-1.9.0-1.20.jar
• Jade-1.20-fabric-11.6.2.jar
• lithium-fabric-mc1.20.1-0.11.2.jar
• no-telemetry-1.7.0.jar
• Patchouli-1.20.1-81-FABRIC.jar
• sodium-fabric-mc1.20.1-0.5.3.jar
• travelers-backpack-1.20.1-9.1.6.jar
• zenith-0.1.7-1.20.1.jar
• zenith_attributes-0.0.4.jar

Updated the mod and its dependencies (fakerlib, zenith attributes) to the latest available (fakerlib-0.0.9, zenith-0.2.0-1.20.1, zenith_attributes-0.1.0) and the bug is present, when you pick up a spawner it displays correct on the inventory (correct entity and stats) but losses all data when placed on the world
