So I take it that:
1. When there are no hazards, all of the enemies with green borders will start on the spawning tile. If there is only one hazard but two green bordered enemies on the tile, they both start on the hazard.
2. For the elite Stranger tile with the two white bordered strangers and the Monster tile with 3 monsters, all of the indicated enemies start on the spawning tile.
3. There is no restriction on enemies occupying the same tile.
Correct on all counts.
