Okay. SO. [@SadCubone]:
How did you obtain logs and in the middle of a grassy field? Just, you know, out of curiosity. Then there's the issue of leaves; it's been stated to be a grassy plain, so those, too, seem to be out of place.
And... Fire in the middle of that kind of location. Are you trying to kill everyone before this thing kicks off? It's tall grass, so even the smallest of flames could probably light the entire place up.
