one way to reproduce

• start a map with any civ, e.g. Han or Rome
• enter gift from the gods
• build a siege workshop and set a rally point a bit further away with lots of space around
• now build a wonder over the rally point of the siege workshop

• start making some siege, for example catapults
• notice that units often get stuck and/or end up in a frantic behavior

• minimal replay with changeset [27543]
  • attachment:commands.txt​
