Or you could use common sense.

prove how much you can use your common sense to determine the following being glitch or not.
You need to give a clear reason for each event in determining if its a glitch or not HOWEVER, you cannot use Nexon's action AFTER the event to determine because then that is not common sense.
If you cannot, then it is not within realm of common sense

aran farm

I feel like putting these here even though they could be redundant.

Hime pointed out unintended issue
which my friend pointed out
An unintended issue can be masked over an umbrella of terms and, for this event, can be referred to as a poor design, however there were no flaws, faults, or logical inconsistencies within the code.

An unintended issue is a substitute for an umbrella of terms, e.g. glitch, poor design, "oops I could have done it better", etc.
A glitch is a logical error within a code that temporarily renders abnormal game-play or system failure.

Therefore an unintended issue is not specifically a glitch.
If Hime want to say it is INDEED glitch/ error in design, she would've just said so and not use the word "unintended issue"

2. The quest isn't suppose to be available, since the beginning of the patch
