Weird combine bug
 

I have a weird bug when trying to use ancient tome of research to make a combine. Im using sof client and when the book is in a main inv slot the combine button is greyd out, on titanium client its not greyd and combines just fine, same recipe, items etc were used in same book for both clients. Any suggestions? Thanks

bump no ideas?
