the weekly frames are tied to the milestone. if u do 2 frames but 1 is from the last week you don't get the other frame for this week. i did a pulse frame from last week and the sword frame form this week and cause of this i cant do the AR or HC frame for this week even tho i have a ballistics log for this week to do so. when u finish the milestone the frames u haven't done that week even tho u have done them before are not available. probs due to the frame used to unlock it is powerful. A fair fix for this is just to as soon as the milestone is completed switch to the normal frames like normal but don't tie what frames are available to the frames completed that week
