Edit: Many thanks to all of the Glitchen who were generous enough to send me an emblem. It's thanks to your generosity that I now have another icon of Pot. You guys are awesome. ^_^
I always thought the worst thing that could happen would be that I would accidentally donate a nice item to a shrine, but it turns out that wasn't the half of it.
I just accidentally gave my Icon of Pot to somebody.
I go to check and see if I'd used all of that icon's functions, since it's hard to keep track with all 11 of them in my inventory. Yup. So I press enter twice to mine the rock I'm standing next to. Only I forgot to click to close the context menu, and the option that was highlighted just happened to be "give". So by pressing enter twice, I gave it to somebody. If that wasn't bad enough, the person I gave it to wasn't like most of this community: as soon as he realized what happened, he logged off immediately, and my icon was gone. He was level 3, but he was likely somebody's alt character, because if he was actually a new player, he probably wouldn't have reacted by immediately logging off.
Well, I hope that guy gets good use out of the icon that I lost because of my spectacular bad luck. And I hope that, at some point, the devs give us some kind of protection against accidentally feeding animals, donating to shrines, and giving people items, as seems to happen so often to people with this game's "spam enter"-based gameplay. Giving and donating things doesn't happen so often, I know, but I hear people complaining how they accidentally fed animals an entire stack of items all the time.
It's going to be a pain working up another 11 emblems with the already inflated max favor I have now. Even when the hole in my collection of icons is finally patched, I'm sure I'll always remember this day.
