I was playing the first map of the Melvelous adventure and I encountered a bug with Flanking Move. The card is supposed to be Cantrip if you don't end adjacent to an enemy, but when I selected my Warrior to move next to a Large Creature he still got the Cantrip effect despite being adjacent to an enemy. The character in question is the Dwarf with the red shield, "Mrs Poodlefoodletoodle". Immediately after moving next to Melvelous I could use a Raging Strike.
Yeah, it's a known bug due to only the lowest square of the large creature being counted for adjacency purposes. Your human warrior would not have gotten the cantrip effect if he had flanking moved to where he is now. The same effect can be seen with e.g the various jumping lightning spells. The dwarf above is counted as one square distant from Melvelous, the human is zero squares distant (e.g adjacent) to Melvelous. This gotcha property can lead to unintuitive happenings in single player play.
We definitely need to fix this before introducing large figures in PvP (leagues), but yeah, for now it's just gotcha events in PvE. Sorry, Maniafig, if this inconvenienced you or broke your immersion. It's a known issue and we'll deal with it as soon as we can.
