So this has happened to me several times across multiple updates, and I have no reasonable explanation for it, nor have I found any patterns that trigger it. Basically, when I play Slayer into Bone or Void, rather than block their energy drains until the standard runs out of time or energy, the standard just stays in play without doing anything at all. I have noticed it to mostly occur in War.
The following screenshot is my proof of this glitch's existance and occurrence. Notice the fact that over twenty seconds have passed against an opponent with a Bone Dragon, yet my standard is at full energy. This means that it has failed to block any energy drain from Bone at all, including energy drain from his orange skill and other skills used afterward.
Please help me! @DSKenshirou_X
