Just started to encounter an issue with my trainer, when i "activate" it the activation sound will loop until i kill the trainer now this is only the second time I've ever encountered this issue, any potential explanations for this, as for AV I have all my trainers written as exceptions.
the only explanation is that the keyboard cache on your computer is flooded with keypress data. this can happen due to the way the game polls the keypress conflicts with the way the trainer polls keypresses in some instances OR you legitimately have a problem with your keyboard.
this is generally fixed easily by rebooting the computer to flush the cache.
best,
Cal
