Code review comment for lp:~widelands-dev/widelands/bug-1573968-new-map-crash

I think it's the buildhelp overlay what's causing this. I can reproduce this now as follows:

1. Start editor
2. Deactivate buildhelp
3. Place player (the buildhelp should normally be activated, but it isn't)
4. Save map
5. Load previous saved map

Crash.
