Greetings! There is a slight rules question with the game, which our local gaming group has started playing.
In the Shadow Vault map, there is a river, which connects the different map pieces together, and which you can swim across, according to the rules. However, the core rules say you can't move through an enemy creature. So the Overlord has just been parking cheap monsters along the entrances to the river, making it impossible to use at all. Is this legal? (well, it's legal currently according to the rules, we think) It just seems as though this shouldn't be allowed, or there should be some way to move along the waterfall even if there's spiders blocking the entire river.
Thank you for the assistance.
