Trefezex: After the fight with many minotaurs, where you have to kill one of them to take a pole to open a gate, there is a pool you need to cross. Now, to cross the pool you have to expand a bridge with a mechanism on the other side. The problem is: the blue minions won't use the damn thing. I can make them to reach it using the flag, but then I can't make them use the mechanism. I tried to select the mechanism and to send them directly there, but the minions get always blocked somewhere... I saw a walktrough on YT, and there everything works fine, but I am stuck there.
Is this a bug? There is some trick a could use to resolve it?
It's been so long since you asked this question that I hope you managed to solve this by yourself, but either way this should be answered for people who will eventually have the same problem. Plus, the lack of a reply was bothering me.
From your description I think you're setting your minions on the guard mark (the "flag"), and then moving the flag by pressing shift (to select it) + click-holding both mouse buttons. What you should be doing instead is not to use the flag at all. Don't press shift either, just click-hold both mouse buttons and move the mouse around to guide your minions. They'll attach to objects they can interact with this way, like chests or breakable vases and of course the stupid wheels.
I had the opposite problem when I played, I didn't know I could move the damn flags. Until it became necessary at the first Abyss.
I hope you managed it or start the game again because it is an awesome game that deserves to be played til the end.
