In my survival world, I have an underwater base will a trading hall. I left my realm while one of my friends was online, I joined back later to find that lightning had struck 3 of my villagers. The lightning struck through water, a layer of stone, and 2 layers of glass, ignoring the fact that I had previously placed lightning rods right above my base. I did some testing and the lightning rod was in the range of where the lightning struck, so I have no idea why it struck where it did. (I circled where the lightning struck in red)
