Hello Ivan, I have to concede that whichever way you actually release these maps is difficult.
Putting all the objects at least should guarantee the maps work, putting only the new additions could lead to issues for players who might not have followed development of the maps and so need to search many threads to find objects used on other maps, dammed if you do, dammed if not, there is no ideal way.
Maybe a option might be to release the maps as a J.S.G.M.E. pack, that way for players unfamiliar with how the static works and possibly without all possible objects available to them could at least activate the maps for a campaign, then again I suppose it would be as easy to save the static you put in and just back up our own so nothing is lost.
In many ways one of the beauties of something like B.A.T. is everything is usually sorted as it develops, however, for someone like Andy that can become a full time job in its own right.
Anyway, thank you very much for the maps, the work you do is always really appreciated.
Take care and be safe.
Wishing you all the very best, Pete.
