Wispwoood events uncovered as "fuel" runs out have no monsters

Like i described, i discovered a monster event (the blue one with the giant skeletton) event with that final flash of light/uncovering of a bigger area of the fog of war, but it had no monsters.

I think this had to do with the new logic in the patch note of "removing monsters inside the fog of war on running out of fuel" from the most recent patch.

The edge of the final uncover touched the event area and uncovered like 2 times the final uncovered area in area of the event.
