How to reproduce: grab a spear and spawn eggs (should work with any). Charge at the placed mob on uneven terrain or block walls (like a tree).
Expected result: the mob should get knockback from the first phase of the charge attack
Actual result: doesn’t apply knockback
Video proof below
Environment
Tricky to explain. For my situation, i was near a tree and uneven terrain, might work in other condition
I'm not getting any knockback with my enchanted spear flat ground or otherwise.
