Roaming queen problem

The roaming queen problem is a condition where one or more queens walk away from their partner hatchery to cast Spawn Larva onto another hatchery. This is a condition that may occasionally occur as a result of the execution of one of the many spawn larva techniques that rely on a single group with all the queens.

At the origin of this problem there is a single click that assigns the target of a Spawn Larva activation on a specific hatch that satisfies one of these conditions: An easy workaround is to issue the Stop command after each round of castings. with the drawback that if the Stop command is issued too early, it will prevent queens that are slightly out of position from casting the Spawn Larva.
 * that hatch is partner of no queen (e.g. its last partner is dead, or she has moved to another hatch)
 * that hatch is the partner of a queen that has not been added to the queens group
 * the partner queen of that hatch has not enough energy (e.g. because its energy was used to cast Transfuse or Spawn Creep Tumor)
