Major Drill asked me to add a sticker to a friends album. I bought two stickers. I got a server timeout error while sticking them.

I tried again, both of them gave the same error and the stickers are gone but major drill still feels I should stick a friend.
I don't really care for the sticker since they were cheap, but it might be a problem.

[edit]

Tried again, now I just a blank page. got the subeta banners and everything but it was just filled with blank space.

It is the same for me. My friend is offline, so I cannot check if they've recived the stickers, but Major Drill is not counting them.

Another similar issue is with "send gift to a friend", I've got blank page after sending, but this time Drill counted the quest.

Yup, this just happened to me too.

Same for me. T.T

Same here o.q

Same for me. T.T

I've checked - stickers are not lost, they are in my friend's collection, it's just blank screen after sending + Major Drill not counting them.

Guys this is fixed now. If you lost anything because of this please file a ticket. Thank you for your patience!
