And i see housing is the original way correct? With keys. Not "I wish to secure this" and set it to friends/owner only. etc. Meaning if I get into someone's house I can steal from containers?
Apart from secure containers, houses only have a few of these and everything else in locked down boxes... So get in and you for it all

So why lock your doors if people can't get into secure containers? Also why is there a limits on lockdowns/secures? Is it same or less than offical server? Is this the reason why there are no plots left? Same person has multiple houses?
