User Description

I was playing triplea, updated to the newest version. I was playing the ww1 version and i tried to use a battle calculator. It gives me an error saying i dont have a null point. I dont know if its something to do with the map, or the current version of triplea. I know im in a testing stage for the new version., so i expect bugs, Im not complaining. Anyway have a nice day!

Might be related to https://github.com/triplea-game/triplea/pull/12783, since it changed the code in question.

We would need a save game from the author. Linked to issue 12897 with same title.
