1. You can use ZoneManager and simply set undestr true, ATMs was supposed to be at safezones, atleast that was my vision for it. Anyway Im adding this on my list for next update.
2. Im not able replicate this issue, spawned vending machine has disabled default interaction. Only what I can see as issue is, players can rotate vending machine outside of safezone but still they are not able access administration menu for vending machine. I will sort problem with rotation in next update. Edit: I see now, issue occours when players hold E while vending machine is not in safezone. That can be solved with placing TC behind vending machine for now. I will 100% look into some solutions.
3. Not planned any time soon.
