I had always played that the returning to site of origin happened immediately when movement for the illegal-making company was declared (i.e., it was the first action declared in their mh-phase, like an extant Snowstorm). It would seem, however, from this note that it is not till the end of all mh-phases that they are sent back.MELE rules wrote:Note: If two companies end up at a non-*-Haven site and combining those companies would violate the limitations on company composition, one of the companies that just moved must return to its site of origin. Similarly, an effect that causes such a violation is cancelled (e.g., We Have Come to Kill).
In fact, this makes sense. After all, you could lose some characters in one or both of the companies (one of the leaders, for instance), resulting in the combined company being legal.
Does anyone know when/if this is clarified/overruled elsewhere?
