Fleet of 40+ orbs in formation filmed over Lake Michigan — video attached

My friend and I were night fishing on the pier when we noticed what we first thought were stars. Then they started moving — slow, deliberate, in a loose grid formation. We counted at least 40 distinct orange-white orbs. They held formation for about 6 minutes, then began going dark one by one from left to right, like someone was switching off lights. I had my phone on a small tripod and got the whole thing. The video clearly shows the grid pattern and the sequential shutdown. I've submitted it to MUFON. Chicago ATC confirmed no aircraft in that area at that time per a FOIA request I filed.
