Long story short.... made enough gold in a short time to buy a House. A House in which I can store any items and retrieve them later at any time.
Used an NPC to carry items... if they died, even did the very long trek, carrying more than my stamina allowed on long, grueling slow walks after getting the items back from them to sell.
Longer story short.... hate to be sounding so negative and cruel, but you did sell the armor. Everything in the game is choice based, and that was your choice. Just like as a Thief, if I take a Thief job then decide not to do it.... it is gone (except from saying I did in my journal). Hate that I cannot go back and do those specific jobs... as they change.... but that was the choice I made. Sometimes svcks...but I'll take a Free Will styled game any day over cookie cutter.
