Thanks Jules! About the AI, I expent a lot of time in the customization, the principal mechanic in the game, so the AI was made in a hurry. About this bug, I'll investigate it. Thank you very much for your review!
I think i know this bug, when you reload a scene, it sets the time scale to 0. I think all you got to do is set the time scale to 1 at the beginning of the level
