I made the first quest 4 wood logs and turned on fuzzy for any type. then when testing it the game crashes as it tries to go into my inventory. I then removed the quests folder to check and was able to pick up wood without crashing.

full crash report: HERE

minecraft: 1.11.2
forge: 13.20.0.2230
hqm: 1.11.2-5.1.0alpha2

Do you still need a list of mods or was Mcjty's comment the fix?

His comment is enough

Ok great. Thanks for looking into it. Keep up the great work.

Is only hqm installed? I tried serval times to reproduce it the last days and I can't. I'll try with your explanation

canitzp, this code is wrong:

        items = NonNullList.create();
        NonNullList<ItemStack> mainInventory = player.inventory.mainInventory;
        for (int i = 0; i < mainInventory.size(); i++) {
            items.set(i, mainInventory.get(i));
        }

Basically you make an empty list with NonNullList.create() and then you directly 'set' items in it. 'set' does not automatically grow the list. You need to use items.add(mainInventory.get(i)) instead

@McJty can you look over the fix and say if it should work

It seems ok at first glance but not very efficient as the code makes a copy of a list of items just to count something? If it isn't used much then that's fine

I only fixing code at the time, there is a lot to rewrite. It is not an perfect port
