If Hearthlings elect to empty their backpacks while traveling up or down a ladder, the entities that they were hauling can get stuck inside ladders,. (Re-)moving the ladder will free them. Reloading isn’t a reliable method, as I’ve seen them persist.
Steps to reproduce:
1) Build a ladder and place it logically into the world.
2) Create AI paths that require hearthlings to place/use them.
3) In the case of mine ladders, you’ll occasionally see blocks of various resource types like coal, stone etc get stuck approximately 1/3rd of the way down the ladder, from the top.
If there is no room left for them to haul their lunch, they should first empty their backpack at their destination (finish their active task) before stopping to eat.
Hearthlings empty their backpacks when traversing a ladder, or at illogical times, such as at lunch time, when this issue tends to happen more frequently.
I know this one has been reported a bunch of times, in various forms, in the past, but since some of them date back a year or more, it seems important to note that it’s still a thing.
