Waiting forever to get a SUROS Regime, Xur finally sells it, I immediately jump into a nightfall after buying it, SUROS Regime drops. Same thing happened with Thunderlord. The only difference was I bought the Thunderlord (I think this was my last exotic in my collection for year one other than Necro) and a couple days later it dropped from the VOG chest. Next week, it drops again from the VOG chest and from a Nightfall. Was quite pissed.
