you are using the version for buildcraft 2.x.x version you need to use the one for the 3.x.x version
Oh...sorry I forgot that I updated it like 2 hours after i posted the error log :D.
Also I found out that this not in fact a problem with achievements. It happens only when I try to make a reinforced iron ingot using VANILLA furnace ( all others work ( EQ-Exchange furnaces and bluletric furnace from RP2))
what version of forge are you using
edit:
i noticed you are using the wrong version of teleport pipes now called additional pipes
I have Forge 1.3.1 . I didn't update to 1.3.2 because It's glitchy with the portal mod
and what do you mean by "wrong version" -_- I'm using the one direwolf20 uses...
with it i can't even open my world for some reason 
EDIT: used a different one and this is what I got:
I was cooking an iron ingot and when it completed cooking my game crashed because of the achievement.
help please?
I get this error on launch.It is something about the recipes but i don't know exactly
Oh, Thank you 
i got really confused xD
oh btw: I love the blue radiation <3
edit: forgot to ask: will it work wit the advanced machines addon ? (Rotary macerator , singularity compressor , centrefuge extracor).asking because i only use those atm.
edit2: gah, my brain is like a mess.will you be doing the items too? (ingot textures , tools etc.?)
How do I install this? the link to block_0.png has 63 custom textures but the link to IC2_retexture has less.Witch one do i use? 
when I use the alpha 2 all the textures are pink , but when i use the texture pack link i dont get all the textures O_o.It's too much of a hassle to change the textures using the source code in the mod that is provided in the op.there should be like a .properties file or something -_-
