No "Share Container" UI

Big and small water catchers aren't private items, anyone can open them and take water

Unless that changed in the latest patch and was not in notes, that is incorrect. They have always been private and you can share them to make them public. 

Last wipe all water catchers were also public and you could drink or open to fill bottles, i know in past wipes i could drink from random water catchers not sure on opening to fill bottles( maybe i was lucky and found only ones that people had shared).

Now i do think they should be private and sharable as with farming now people could screw people by taking all thier water
