[galaxy-dev] novice galaxy user needs help retrieving MIA history

Greetings, I am a novice Galaxy user. I was getting along perfectly this morning (made some mistakes, deleted some steps) and got to alignment steps in my RNAseq analysis. Went to some afternoon meetings, returned & logged back in- MY HISTORY WAS EMPTY! can you advise? Instance: MAIN/publicUsername/email: jnkaccnt1@outlook.comHistory name: something like "LUAD RNA-seq"; definitely had "LUAD" in title also, here is one of the steps/filenames that should be in history (I downloaded before meeting):"Galaxy240-[H1648_TopHat_on_data_164_and_data_163__accepted_hits].bam"

any help sincerely appreciated
