4th Fastpasses

Does anyone have details on the 4th Fastpass option happening this week?

There was a thread on chat about some people getting extra FastPasses today, then I saw Kenny the Pirate post last night that he was able to reserve an extra one today. Beyond that, I haven’t heard anything about whether this was a mistake, a formal test, or something else.

The people posting say its giving a bonus 4th fpp until April 1st only. and that once you’ve been given it you can change it to something else. Nothing official though.
