Code review comment for lp:~widelands-dev/widelands/bug-1759857-territorial-lord

Yep. I had quite a bit of fun with the refactoring in this branch, because a nonexistent variable is simply nil, which Lua will happily process... So, if you rename a variable, you better don't miss any instances of it!

Thanks for testing and the review :)
