icydk, Yostar released Beeswax and Chiave in EN during Grani rerun event. They instead released Joint Operation 2 banner for this CC (maybe they wanted to accelerate EN to catch up to CN that bad I guess).
EN skipped a lot of dead weeks and had to fill them with events until anniversary. they also moved Beeswax and Chiave Banner to Grani rerun and move Joint operation from The Anniversary second part to CC#2.
