I'm guessing you need to right click > run as administrator? That or make sure the game is closed.I can't get the editor to work at all. Every edit I make is unsaved, regardless of what changes I make or how drastic they are, I always get "save saved successfully" followed by nothing actually changing. If I save and then open the file again, nothing is any different. It doesn't seem to actually save.
From experimentation and according to the wiki if there is an enemy owned hood borders that hood that you own as long as it is the same gang that owns it say the brotherhood own huntersfield but you own wardill Airport one will trigger but something the wikia said that i have found otherwise is that if a neighborhood is under a pushback and you own a neighborhood bordering it it will spread i havent tested but sounds possible on sr1 but i know isnt true on sr2This was stealth updated in February of the present year to version 5.1.0.0. No clue what's new or different in it at a glance.
I wish it let you choose where to save the launcher/editor(s)/save backups, if only to have them not occupy space in a partition with an OS in it or to be more easily portable if users want.
New function wishlist-wise, I'd like it if it were possible to set hoods' active pushbacks or edit the currently stored pushback countdown(s) for SR2. I want to see if there's unexpected behavior if you try to force a hood that shouldn't have pushbacks happening in it for whatever reason, assuming the save file has relevant fields for all of the hoods (ideally it shouldn't have them for the three unconquerable areas nor the three gangs' final unlockable hoods).
