Arena doesn't seem to start waves properly

[tehvappy50]

Apparently when you select which wave you want to fight again, it decides to go one extra number backwards (as well as giving the start next wave/stop arena prompt). If you choose "UAC Outpost" in the new game prompt and just run to the arena and activate it, you will start on wave 0. Also, holding either the use or the run button just as soon as you kill the last enemy or run into the active arena (and having the prompt show up) will immediately start the next wave or end the arena (though it doesn't seem to affect the first prompt on outpost (re)visit).

Just leaving a note here to say this might become a moot point when the arenas are re-coded and completely redone.
