Bad unit tx "set_think_output" from "ready"

Error:

CHECK failed: C:\rb\ihome\root\SH-OB0-BUILD\stonehearth\source\lib\lua\ai\execution_unit.cpp:205 bad unit transition “set_think_output” from “ready” in action pickup item type

Steps to reproduce:
Unsure what threw the error. May be caused as a result of continuing from an existing save that predated the current unstable release. Some generic actions included:

  1. Attempting to undeploy fences while there may be no space
  2. Removing ladders
  3. Placing storage supply shelves on a building (the carpenter’s house is requiring one more item in order to be considered complete by the building designer dialogue window)
  4. Changing the filtered item on a supply basket from silkweed bundles to eggs. Changing the filter on an egg basket to frostsnap flowers in order to allow the hearthlings to pick it up.

I got the same error. It turned out to be a hearthling stuck on the mason’s workbench. check all your hearthlings and see if anyone is stuck somewhere. If you’re mining one may have mined themselves into a hole, if you’re building one may be stuck on a building, etc. Just check all your hearthlings and make sure no one is stuck.
This is my error.
