Same issue as #32 :)

sorry, I had posted the wrong log, i think now i posted the right one, my bad

i asked ladysnake if they can fix that. That locki library is from em.
They said they'll try to make it compatible again and if that wont work they'll delete the compat code so that it wont crash but will work suboptimally

Alright :) I will leave #32 open instead of this one
