Workarounds are usually used in context regarding to bugs or software problems, as it seems like the devs intended this, my solution works perfectly for me. Semantics and perception. I have no issue with not allowing the energy bar to "overfill" as it has only happened to me once. Those that choose to collect missions with a full energy bar do so knowing they may waste any energy possibly gained.
Not arguing this further, you don't like my solution, don't use it, but to only comment by saying I used the "wrong" word and to correct it seems petty. Have a good day.
