Reproduction:

1. Acquire a wand (the limited one) or an artifact gun (unactivated will work too)
2. Fire until it runs out of charge
3. Get another gun (fingergun will do)
4. Activate combat mode and choose the fingergun
5. Fire anywhere
6. Watch in confusion as the anomaly gun/wand fires along with the gun (the wand also goes into negative charge and can now fire infinitely without the whole other gun shtick)

this can honestly be fixed extremely easy by probably changing the (fire if charge !=0) into (fire if charge > 0)
