===========
Also, I've been using Cleaning Robot for quite a time now.
There is something did bugs me on v104.
Though, I am not sure if it is indeed a bug, or there just a limit on how many Max Energy we could get.
Apparently, my Max EN doesn't increase, when the event says it supposed to increase.
The event says that I got 3 point increase, my current Max EN is 260. and it doesn't adds up that 3 points.
Event location is on the Hallway > Cleaning Robot.
