My Science character has been running into two graphical/sound bugs when using her Science kits.
If I apply Tachyon Harmonic and I am hit by enemy fire mid-animation, the lens flare from the Tricorder persists. Sometimes it is cleared if I can apply TH again (without being interrupted), sometimes not.
Also, the Tricorder seems to remain in the characters hand all the time after the first use of any ability from the kit. The Tricorder sound also persists and will not stop playing, even if I am not using the Kit or in combat.
