YOu can't light the fire when it's raining! BUt when it's raining the fire doesn't go out! Weird!

why did you wait for it to rain to start the fire to find that out? or did it just happen to be raining?

I figured that out too!! Only it happened to me when I finally realized that the torches were used to get rid of the bees around hive! I felt double dumb!!

it took me hours to find that one out needles to say i felf dumb

I just wanted to light it and tried as soon i could. I was trying to make it rain.

Not so weird. A large fire will burn out raindrops quickly, unless it's a heavy rain. However, already-wet wood needs lots of dry tinder to begin burning.

As soon as the rain stops the fire can be lit. I reckon the villager should be forced to fetch some new dry grass; surely if it's been lying in the fire pit during the storm it won't dry out immediately?

It's an effect of the super-bright tropical sunshine. You live in London, where it never stops raining, so how would you know?
