This comes in two parts. Firstly as you can see from the screenshot i have only got two available legendary frames available which are bow and sword. Previously, all of them were available and these two are possibly available now because i completed them before. Secondly, These legendary frames do not count towards my progress in Giant's Might or Butterfly's Grace.
Same here only got 2 frames ... Machine gun and Automatik rifle .. . A fix world be nice
