Sorry if this has been covered already but I couldn't find the answer I was looking for in the rulebook or by browsing this forum.
When reinforcing large creatures, is there any kind of "or closest empty space" clause in terms of where your creatures spawn? If I'm to spawn, say an Ettin (4-tile figure) at the entrance, but a hero or a familiar is standing on one of the four entrance tiles, am I not able to reinforce? If that's the case then heroes could effectively prevent OL from having any reinforcements by simply leaving a familiar to stand at the entrance and then carrying on with the quest. If there
is
an "or closest empty space" rule in the same situation, then the monster re-spawning would effectively be three whole spaces ahead of where it was supposed to spawn.
Thoughts?
