The Bug
Stage 2 (the "tired" stage) of the spear's charge attack has its animation incorrectly slowed down depending on its duration. This causes the spears with lengthy stages (such as wooden spears) to rotate very slowly and reach their sideways state later shortly before Stage 2 ends.
Expected Result
Stage 2 animation lasts different amounts of time, like other stages, depending on length.
Observed Result
Stage 2 animation’s transition is incorrectly slowed down whilst the animation itself lasts a constant length, causing broken animations on spears with longer stages.
