My understanding of "historical" is that, yes, lightning will strike, and yes, it may strike wooden structures catching them on fire, but no, it's raining and will MOST LIKELY put the fire out before much damage is done.

We are having constant issues with wooden fencing containing farm animals blown away, letting our mobs escape, having wooden bridges and wooden roofs burnt away. "A" random wooden block being burnt once in a VERY long while. Having ongoing issues with wooden structures taking significant damage over time from storms sets up "don't build with wood EVER, don't plan on nice looking trees EVER", and so on.

This isn't griefing, as there are only four of us: my wife, her adult son and my adult sister, and we are all being affected by this, and it's ... pretty random, as if lightning is setting things on fire without the rain putting the fire out.
