The Sigma & Octantis' combo inputs are broken regardless of stance used

[Twilo101]

Regardless of whether one is using Eleventh Storm or Final Harbinger, the Sigma & Octantis always does the first hit of the neutral combo before any given input, including slide attacks. The weapon still functions aside from this bug, but it breaks the flow of combat quite a bit with slide attacks, block combos and forward-block combos. Aerial attacks are not affected by this bug, either because they're not affected by stance mods, or because of the Sigma & Octantis' unique throwing mechanic.
