Andor's Trail

In "Devastated land", after finishing the quest with five wings, Hadracor should give the gloves if you find the sixth wing; a new log entry should be created.

Hadracor gives Woodcutter's gloves if you finish the quest with six wings.
Getting the sixth wing does not look like a bug because there are six giant wasps in the code.

there is a difference between presenting the 6 wings at once and presenting 5 and 1 later. I'd say both ways are plausible.
Although one could argue that it is a bit unfair to give the gloves only in the first Version, I'd rather let it the way it is, so the extra reward is a bit more hidden.
