"Enables the use of mining productivity when using mods with machines that create ore (rather than mining drills). All crystallizers now receive a bonus from mining productivity research, the same way that mining drills do in a normal game. Designed for use with the Sea Block mod pack, but does not require it."
updated to apply to crystallizer 3 using "Rashino"'s fix uploaded for your convenience...
if Minno comes back to the modding community and wishes me to remove this all they need do is ask
ps. if after researching mining productivity it doesn't apply, try saving then reloading
