Fix Version/s: None
When a mob transforms into another mob (ex. zombie villager → villager, mooshroom → cow), it loses most of its NBT tags. This also affects conversions to the same mob, like slimes and magma cubes splitting.
It is worth noting CustomName and NoAI are preserved (
MC-6773 & MC-67437), so other tags are expected to be saved as well.
The following is a list of tags that aren't transferred between entities.
|From||Zombie||Zombie Villager||Mooshroom||Slime||Villager||Piglin / Piglin Brute|
|To||Drowned||Villager||Cow||Smaller Slime||Zombie Villager||Zombified Piglin|
- Summon a zombie villager with above tags
- Once the zombie villager converts to a villager, look at its NBT data
→ Note that the tags do not persist
