Hi! Just as a heads up, I have no clue how replacing player models/animating works, but it seems the emotes are incompatible with the emotes from the Quark mod, as the animations for the emotes don't seem to play when I use them. I don't know which mod needs to make a change to fix this, if possible, but I will also write this report to the Quark authors in case this issue is not yours to fix. Thank you!
(Also, I cannot seem to break boats with melee attacks. Same version)

Turn on the "Filter Animation" option. It'll stop the animated model by Epic Fight in mining mode. And the unbreakable entity bug is fixed after 4.1.4.
