No harvest tools in Dawn's Harvest

I wanted to do the side mission “Dawn’s Harvest” in parallel with “The Cult of Personality”.

  • pick up Dawn’s Harvest mission
  • pick up tools
  • pick up The Cult of Personality
  • pick up the first few mission items
  • could NOT pick up the shovel for the main missin because I already had one from the side mission
  • planted crop, watered crop, harvested 10 corn
  • put maize on truck, fought with guy

Now my shovel is gone, I cannot pick one up anywhere and I still have 20 corn to harvest. No shovel in the mission items. No shovel when you run into the mission area.
