Also easier to take cheap shots and condescend to someone “new” (infrequent poster, at least) to the forums who might not know as much about game mechanics as veterans like yourself rather than use some charity and patience in explaining the mistake thoroughly, and with sympathy.
It’s not crazy for a player unfamiliar with the game’s general mechanics or who doesn’t frequent the forum enough to know to peruse the (often incomplete anyway) patch notes to assume that a Palooza is a “gnome event” trigger. For 15 minutes, as opposed to a weekend. That’s not how it works, as explained above, but for any player that thought it was, “wasting” the hard-earned Palooza by crafting at an inopportune time sucks.
So maybe the better tact for a Positive Petra to take would be: “Yeah, man, sorry about how that happened to you. Sucks to waste those verses chasing after the keys you thought would be there in abundance. But hopefully you got some good stuff besides, at least, and now you’ll know better for next time.”
If they hit back after that, then fine — be abrasive. But out the gate? Poor form, indeed.
