A strange stop moment.
It is mechanically impossible to step onto a cell occupied by another character -> this reveals invisibility.
It is impossible to change a move mid-action -> if an action required moving to a specific cell and the movement was stopped by an unexpected block in the form of an invisible unit, you can no longer complete it.
Lorican was going to move 8 cells down and restore health, but along the way he ran into Lester, revealing his location...
In this particular case, nothing prevented him from drinking from the flask at the start of the movement.
+ Stop replaying moves already.
