Mad respect for all your hard work. Wife, kids and myself have been digging holes since you dropped the world generation update and having a blast. A few things we've experienced/noticed:
~ If multiple people are in chests one person closing theirs will close all chests open
~ If in your inventory and someone closes a chest it closes your inventory as well
~ If you die you are unable to claim your gear from your body
We will continue to document. Can video capture as well if needed. Thanks again for all y'alls hard work.
It requires a few bigger changes, so maybe it will be fixed with the upcoming NPC update (or shortly after the NPC update)^^
Texas has your back. Great work here. In the mean time is there a way to change permissions to keep inventory for the children.
