It's fine, don't worry about it.
Just a bug report. These things happen.
The next time I do an event that I've done before, will it reset or carry on? And if it resets, will I get all the bonuses again?
Another thought I had for the game is a BUY ALL button for the NEXT button at the bottom of the page. With each prestige, this is becoming more and more tedious.
Alternatively, put the NEXT button in the middle of the screen below the line of text so it stays in the same place, making multiple clicks of it easier.
