    Let's do a guess from what i can understand of it. Are you really sending your PIC i/o directly to the base of your TIP122 without any resistor in serie with the base? if so... your problem is there.

    Also, as those transistor have already resistor between base and emitter.. you don't really need those you place.

    If you don't want to do PCB modification, you change your TIP122 to a mosfet, some, see all, Logic type can be driven without resistor in serie with the Gate.

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.
