[2021] Subsumed Dispensary plus another lengthy cast animation=broken weapon

I copied your account and this doesn't happen for me using your steps of, "use dispensary, then use sleight of hand afterwards, then fire your weapon(while your hand is still out from casting sleight of hand)".  Could you record a video? (using the powers you've already installed overrides for)   Is there anything unusual about your input configuration that might be part of the issue?
