possible evil box glitch?

For Nexon to have actually implemented a script like this is extremely unlikely. It means adding a database entry for every account which will contain the number of "premium" items received, and that entry would have to be reset daily.

If you have no programming knowledge, you're probably thinking "that seems easy. it can't be that hard". It's not about easiness - it's about likelihood based on what Nexon's done in the past and the amount of effort they're likely to invest for such a trivial event like this.

Nexon doesn't go messing around in the database just to add junk info like that. That's my 2cents.

Your two cents are woefully ignorant.

You act as if Nexon would have to build some new architecture to implement such a counter.
Well, you're wrong.

Tell me, how does Nexon's database know whether an individual character has already entered Zakum's Altar twice in one day?

That's just one example. Another would be the 10 run per day limit on every PQ that was just added.
In reality, such a counter can be implemented as easily as it is to add any daily quest.
The only difference is that the player has no visible indication of the counter.
