Heres the paste bin for the crash:
https://pastebin.com/4XeSQKkh

The main top argument is:
java.lang.IllegalArgumentException: Cannot get property class_2746{name=waterlogged, clazz=class java.lang.Boolean, values=[true, false]} as it does not exist in Block{lepton:polished_andesite_pressure_plate}

For more information its caused when loading a world that has been pregenerated or newly generated.

I'm going to double check if its mod incompatibility or a main mod issue as re downloading didn't fix such.

Yeah, it might be that because I tried to load a world or make a new one and it still doesn't crash

Ok so by it self, it works but some mod is causing this issue so ill attempt to find out which.

ok nice

Its seems to be an incompatibility with a mod named Plated. It allows the placement of pressure plates to be placed on walls.

Ah, I see, it might be because we have our own pressure plate class and that's what breaking it, I have to see if I can fix that

Sorry but I can't fix it because Minecraft has protected access to the pressure plate class, so you're going to have to make an issues to plated, to see if they can fix it :(

K, ill see about saying something but could you at least give a warning for anyone who might use that mod with lepton?

sure I'll keep this open and but something in the front page

Sorry, I can't reproduce this but maybe someone else can, are you using any other mods that might do this?

Used the most current one uploaded to Curse. Ill check if the file got corrupted by redownloading.

ok
