This isnt really a question but something I was able to figure out myself so wanted to post incase anyone else has the issue. [br]
After using the back paddles for Rocket League for an extended period of time the button on the back of the controller I was using for boost became hard to press or would not work sometimes. [br]
I found that the plastic that the screw holding the PCB for the underside buttons on that side had cracked and so the PCB was moving when I tried to press the button, making it mushy and sometimes no button press would be detected. [br]
Luckily the plastic which the screw mounted to was still there and I have been able to glue it back together to re-mount the PCB to and fix my issue. [br]
I also noticed the plastic for the screw on the other side was also cracked so put some glue on that side too. [br]
Might be worth a check for anyone else with this issue.
