Are you sure that is what he meant? That is not the way I read it at all.its posted in forums that you jump 1 level regardless of were you are so if you are 15 culture point over your previous level after the jump you will still be 15 culture points over your new level
ps the mods worded this a lot more eloquently in the original post but i could not be bother to look for it, its somewhere in haloween thread
When yo get the CP reward you will automatically get the needed CP to hit your next CP level. Be that 100 CP or 4 CP you'll get it the instant you complete the 45th recipe.
