Some mobs get incorrectly marked as passive

[Etes-Hyene]

Describe the Bug

Some mobs such as the Sabeast from The Bygone get marked as passive despite actually being hostile.

Reproduction Steps

1. Install the Field Guide and The Bygone mods.
2. Enter the Bygone dimension.
3. Find a sabeast and use a spyglass on it.
4. Check the entry for that mob (it's in the animals section).
5. Approach a sabeast in survival and find out how "passive" it truly is.

Expected Result

Sabeasts (and other mobs that have this issue) should be marked as hostile and probably put in the hostile section

the same issue most likely happens with the Macabre mod cuz as i was exploring the dimension in creative i noticed that some rather unfriendly looking creatures were marked as passive
