map_cache files?

[KiraImmortal]

hello there!

i'm making progress with my amnesia - a machine for pigs mod (still i write it down here, cause the experienced modders are all gathered here), i still have no idea how to make it a full conversion mod in the end, but i'm sure i'll find a solution.

now.. what my problem is that editing the original maps of amfp have one little problem. there are files (in TDD also) called map_cache files. what are these for? how is it possible to edit them? i think they're some sort of 'saves' of the map itself, which contains objects and scripts written inside (they're quite big in filesize). when i make them empty, the phone-calls (you know if you played amfp) are not working in game, everything else is fine. but i want to bring those calls back to work, if i don't the cache files, i can't delete any objects from the original maps, they will stay in game.

any ideas?
