Remove the old Plains and Simple zip file from your mods folder, download the new file from my google drive, unzip the Plains and Simple Fix4 and place the Plains and Simple map zip into your mods folder.
Small fix to the gates. The old embedded script has been removed from the map so the issue with gates not opening should never happen again. Gates work via exiting the vehicle now by default, to open and close them from inside grab Blacksheeps Animated Objects Door Fix script update and place it into your mods folder. It can be found on the official Giants mod hub.
