Got a pop-up while clicking through on a battle.
Aug 15, 2017 12:32:01 PM games.strategy.triplea.ui.BattleStepsPanel setStep
INFO: Could not find step name:British withdraw?

Looks like if you fight the battle, then the 'info' line pops up. Not sure why I saw it as a pop-up, opening the error console and then opening this save game and proceeding to battle should repro:
info_error.zip
Is the bug that the step name is missing or that the console popped up?
If the latter, #1950 already covers that issue. Basically, anything going through a Logger, regardless of severity, will trigger the console because the default-configured ConsoleHandler sends all output to stderr.
Former, the info message is not expected.
@DanVanAtta @ssoloff This is closely related to the issues that I fixed in #1954. It has to do with the steps are all displayed in the battle window at the start of the round. Depending on casualties some of the withdraw options can change (think amphib units exist at beginning of the round but are all killed off during round so retreat option changes). I simplified the code to show a generic retreat option to avoid the changing retreat types. I guess there are still potential issues here though.
Excellent! This was one of the ones which I found annoying.
This is fixed in #1981.
Please close.
Closing per @simon33-2's confirmation. @DanVanAtta, please reopen if there was something else you wanted fixed with this issue.
