Double Miracle Time and 2x EXP & Drop Events: 3/14 - 3/15

Having worked in development teams before, I can tell you this is entirely plausible.
In a large software project, one only becomes intimately familiar with the details of pieces they have worked on or are responsible for. Everything else is only known at a very superficial level.
The GMS development team does localizations and "exclusive" content. "Localization" means translating text, and adapting content we get from other services (mostly KMS, but sometimes JMS and CMS) to work right in our unique configuration. As far as I know, Cubes are identical across all services, so our team never had to look at that code.
(Although, as I recall, we once asked very specifically whether Miracle Time applies to all cubes, and received an explicit response that yes, they do. I'll have to search for that exchange. But if my memory is correct, that means someone glibly answered without even checking. I don't like what that means regarding any answer or info we get from Nexon...)

I'm more curious as to what made them suddenly look at that code yesterday, tbh.

And I do admire Artasi's courage in coming forward with the information. (Or whoever wrote the web notice. Or whoever told the writer to put the list of cubes on there). Donxon would have just left it saying "cubes" and let people waste their time. The notice wasn't as explicit as we might have liked, but once someone made a clarification thread on their forums, Artasi owned up. That is nice.

Yes, I'm aware of that stuffs and to be honest I think Artasi is really trying to make things better and I'm not quite certain Nexon wanted him to release that information which means he might not be around for long if that's the case. Him coming forward with the information was most certainly to met with backlash but hey it's info that is rather important to know at least.
I do recall Nexon making a statement that all cubes were effected by miracle time as well which is why I'm pretty skeptical about that statement since I think it was some time ago when they said that?
