Dark Split-Sword mastery

[ShikaRoddy]

Soo, I remember when Dark Split-Sword came out I had just enough resources to build it, so I built it. Even though it wasn't an endgame weapon by a long shot, I still enjoyed it (although changing stances midgame would be so much better). Then, when I hit rank 30 on my melee weapon, both codex and mastery suggested that I was playing with dark_hybrid_sword (or something like that) instead of Split-Sword. Well, this hybrid thingie got fixed, apparently but I still didn't get mastery xp and codex's still not showing that I've masterd dark split-sword. Is there any way of fixing this (because building it is quite pricey, and I don't think it's worth building it twice) or am I the only one to have this problem?

It's a glitch. You still have the mastery for it, just the codex is wonkey probably from when they were still developing it. Like how the kavats have two slots for each breed.

I'm not sure what you are looking at, since, on my profile, at least, It still shows both the dark hybrid sword - dual and the dark hybrid sword-single.  I will agree that the dark split-sword is still dark, and not showing mastery however.
