Industry unlocker
Can be used to lock or unlock all industries on the map.
The asset must not be placed anywhere, selecting the function is enough.
Can be used in existing games, at any time.
1. Select the asset in the category "misc"
2. Press "lock" or "unlock"
3. Finished
Should be save to remove from savegames, unless you actually built it. In this case, lock and unlock the industries again before removing it.
I am not liable for any damage to software, hardware or savegames. Regarding latter ones, I suggest backups.
