I tested and reformulated MDragonX's bug report so that I can clearly understand what's going on:

Repro:

• P1 hold the attack button to launch a KI wave or super attack
• P2 use time stop
• P1 stop holding the attack button

Result:

• P1 fires a Ki Wave during the Time Stop
• The Ki Wave is frozen (normal)
• After the end of Time Stop, the Ki wave loses its tail (not normal)
• Same for all Ki waves and Special Ki waves
• No problem with Bombs

I'm not going to fix that, that's actually a good way to fight against time stop 😁
