[1.3.3052] Long rope to the pen animals after caravan disbanding

[fstLEo]

1. I removed all the caravan members except one, which was far away. Then I also removed him and he tried to lead the animals with the ropes across all the base
2.
3. More realistic lasso skills
4. Start gather a caravan with the pen animals. Wait until packing ends and caravan starts moving toward the exit from the map. One colonist should be far ahead of the caravan. Remove all the other people except him. He will lead the animals with long rope across all the base. (perhaps it happened after I removed him from caravan too)
