There is nothing new about this bug, as it has been in the game since forever. I once suggested
options to disable the new event alerts, or better yet to disable specific types of event alerts. I was told that the alerts are supposedly used to stop bots, but I don't believe they have the desired effect - if someone can create a bot that clicks on buildings and collects production, it should be simplicity itself to make the bot close the alert whenever it appears. Therefore this feature only harasses legit players.
This bug has been reported at least
here, and probably several times more both before and after.
