Trickshot aspect removed from collection - unobtainable now

Console Bug Report
1

Unlocked trickshot to use of rogue via my higher level character.
Using this character I attempted to put the aspect onto a rogue weapon ready for it when it levels up.
After switching various characters and playing, the aspect is no longer in my collection and cannot be obtained by completing the dungeon.

Rogue build is now blocked.

Same, the two (perfect) aspects I collected no longer show in inventory, but I can still use the weak one from the dungeon.

Is it me, or have they been replaced with the ‘lucky hit/arrow storm’ aspect?

I’m hoping this is a bug.
