I don't have him unlocked, but I can certainly concur with the server hiccup you referred to! During that period of time, all the local stations that sell bulkhead upgrades for the Python were suddenly out of stock. When the server got reset or whatever happened on that end, it fixed this glitch and those missing bulkheads were back in the station inventories they were supposed to be in.
Sounds like just the opposite thing happened in your case. An asset that was previously in-game is now missing. This seems to be an ongoing theme with the 2.1 release and point update, going all the way back to the first days after the 26th of May, when many of the Rare items went missing from the Commodity Markets of the stations associated with them.
Don't know what is going on, but I have never seen so many instances of various in-game commodities, modules, NPCs etc. disappearing from the game without warning. Only to return later with no comment or explanation from FD as to what the heck is going on!
Have you filed a bug report?
I did for the missing bulkheads, and soon after that, they reappeared.
