When I click 'start looting' character atempts only few times to pick up the chest(IDOC did not collapse yet)
I am afraid that it won't pick them up once the house collapsed.
There are other looters you can find that will continually focus an object(s).
If there is a specific item you want at an idoc, use another account and a specific/focus looter with one item id.
This strategy on more than one account will significantly increase your chances to loot the item.
The more IDs you have on a mass looting string, the less likely you are to gather the items further down on the ID list.
When using mass looters prioritize your IDs so the most desirable are looted first.
Hope this is useful information, best of luck!
