i just doesn't let me load my world :(

It looks like some mod is adding or removing furnace recipes from a different thread. Do you know of any mods you have installed that are doing changes to the furnace recipes?

it's cooking for blockheads i think. if not, it's IGCM from CreativeMD i'm %100 sure.

Cooking for Blockheads does not change any recipes, it's only trying to read them at the same time as some other mod is trying to change them, which caused the crash.

yeah @CreativeMD should take a look, i think...

Yeah IGCM changes the recipe list every time somebody changes the configuration. @KenyMylankca if you don't this feature anyway you can disable it in the config file (make sure to disable it on client and server).

uhm, i'm using it actually, i tweak recipies with IGCM... :/

Also furnace recipes (you can disable that separately).

oh i will do that so.
B:enableFurnace=false
by this way, right?

Yes and make sure to disable it on the server as well (if you are using a server).

thanks a lot. i disabled it.

If it's confirmed to be IGCM changing the smelting recipes outside the main thread I think it's worth investigating why (though looking at the code I couldn't find any immediate problems that could be causing this).

Actually, not outside the main thread (if I'm not mistaken).
