I believe there may be an action amount bug. I barely did anything today, yet apparently I had already commited 1500 actions. This is what I noticed leading up to the action limit. I had already commited 1493 actions and had 7 left. I click twice and that gets me over the top somehow. Now, if my math's correct, I would only have 1495 actions after the two...
This led me to believe that all my other actions were hugely increased too. Likie for every click=7-10 actions. I also do much more on CN:SE, and have never even remotely (like 1200 out of 1500) reached the action limit (I recruit a lot, so you know probably know what I mean)
