I see a bug at level 4. Most of my marksmans get stuck at the start. They don't move forward.
Hi, Tuloski! Sorry for long answer.
Are you sure that this is a bug and they are just stuck?
They can get stuck in the bushes of the cursed forest.
Bushes and lightning is a feature of this level.
Bushes can protect your shooters from melee enemies.
Just from the experience of past levels, it is worth remembering that everything in the game is clickable.
