This stuff happens in all MMO's not just here. If you had any knowledge in gaming (Which I highly doubt.) You would know that MMO's are the heaviest with coding and changing the color of an item from blue to green could do as much as break your inventory entirely.
Except most MMO's dpn't release things like this live intentionally. They actually test it internally, or through a public test server. Things actually being broken completely are pretty rare with the successful MMO's now, except this one of course.

All today's patch.
