Guild Wars 2

done all fractals from 1 to 65 and funny thing is i can open max 63 lvl.
why ? will it be repaired … or just new feature ?

You most likely did not do them in order. Meaning you did 63,64,65 at a time where your personal reward level was lower and later did some low levels while your personal reward level was higher.
Your personal reward level (which determines what level you can open) increases only if you do a fractal scale equal or higher, but it only increases by 1, even if you do 100 while you prl is 1.
