Map size management hints for long campaign
 

While most players know by now that you can reset the map size in the repair screen, there's a few tidbits I don't believe are common knowledge.

1) The map size used for special missions (which skip the repair screen) is the map size you had specified in your preferences at the time of creating the campaign.

2) It is possible to change the map size during the purchase of support units. Go into the map view, load a custom map of the desired size, and then use any of the random map regeneration methods to create the final map. The size of the resulting random map will match that of the custom map you loaded.

This 'map size forcing' method can be used if you accidently forget to set the map size in the repair screen as well as with special battles.

Hope this helps someone,
