i've tested a little more.
any two keys pressed at the same time will get this error.
please have a look at it. :)

Are you still using an outdated NEK? Latest is b29

This has been fixed by version b29. See: #20 .
The next version of the DW20 pack will have the updated version of NEK

I'm using the version that direwolf20 modpack 1.0.2 came with.
It's b12,I think.
So this is fixed?

That's great, thanks. ;)
