Platform, device version and operating system:
What you were expecting to happen, and what actually happened:
I had expected to get a flash offer for a weapon on Monday, but there was only the new 2 week summer deal right now.
Today, Tuesday I got Stonehammer. I expected to get a flash offer to upgrade the troop and there was none. It was the first new troop I got today, so I had not got a new troop offer already today.
How often does this happen? When did it begin happening?
Just noticed this Monday and again today. It did not happen when I got The Lord of Slaughter on release day.
Steps to make it happen again
I made it happen again by using keys to get Stonehammer.
