I ran 2 Sporefall (LFG/Normal) x23 90 characters.. My vault is flashing, I get the animation as per i.e. they are all flashing on the mini map but when I open them they are empty? Its happened 3 times now so I dare not open anymore.
No addons - Also, checked on 3 different clients, x2 pc & laptop. Just tried a 4th vault, and its the same as above.. Zero content.
Edit - Seems like its the combination of LFR Sporefall & Normal that it doesnt like. I tried another alt that ran 2/2 Raid and Timewalking.. The timewalking options awarded me the choice but not the Raid.
