i managed to trigger one or two crashes, i hope this update fixes it for you.
i took the liberty of attaching an updated version to the opening post that won't mess with your loadout data, and it will actually use the larger map blocks this time, i'll attach it here too for archival purposes.
edit:
if i were more familiar with the maps i'd have sorted them a bit, so you'd have commercial and residential districts seperated, and then further subdivided by their overall theme, ie: suburbs, with cheap affordable housing, plenty of variance in the buildings, and the occasional motel, or housing estates, where only 1 or 2 types of house are used and there are vacant lots and construction sites, or a commercial district with supermarkets and gas stations, or the "uptown" region with hotels and restaraunts, and so on...
additional to this... i'd like to see civilians themed to their environment, like say at a port or cargo ship you'd have sailors everywhere, but at an island resort or cruise ship it would be mostly chicks in bikinis and fat guys in speedos. oh wait... that's my job, and that sounds like something i might actually have to do at some point... (additional edit: this is now done)
i guess it wouldn't hurt to give them (optional) weapon loadouts and adjust the neutral AI to help XCom if it's armed (unless XCom kills a neutral, at which point they are seen as a threat as well)
