Little Logistics crashes with Epic Fight because locomotive engines are being cast as living entities when they're not in line 79 of LocalPlayerPatch.java, I fixed it by adding a conditional that checks if the parent of "hit" is a living entity.

Now there seems to be a problem with monsters wearing armor, ill keep looking

EDIT: It seems that that issue was fixed in the recent version of the beta.

Oh.. I made the code without expecting compatibility with other mods. thanks

Fixed in 18.1.5
