Questions re Map editor

[76mm]

hi, I've just picked up this game and have to say I'm pretty impressed.

I'd like to start creating some maps but have encountered a few issues with the map editor, so have some questions:

1) Numerous places in the manual refer to "batlocs" or battle locations, but I don't see anywhere that provides a clue about which batlocs are associated with which locations??

2) In the manual it says that I can create a winter map and then use the map generator to convert it into a summer map with the same terrain, but I can't seem to do this, because all of the randomizing factors are different from when I created the map, so I can create a summer map alright, but the terrain is totally different.

3) Is it possible to save a map after the completion of a scenario so that building damage, destroyed vehicles, etc., remain on the map for the next battle?

Thanks in advance for any tips.
