Pretty straightforward explanation as per the title. When entering Epic Fight Mod's combat mode there is no issue attacking entities, it is only when out of combat mode and attacking with the normal vanilla punch.

Has been tested by multiple players both on multiplayer and singleplayer, going through the crash log ourselves we can't seem to find anything wrong.

We are using the latest 1.16 version downloaded from the Curseforge

Thanks in advance! :D
