2. Still on the PC version, rebinding the Action key to something other than the default will sometimes resolve the problem.
3. Another solution could be to disconnect from the internet to complete the event.
4. For console users, try placing the controller on a hard surface and press the button as quickly as possible using your index finger. This should allow you to press the button much quicker than holding the controller in your hand and using your thumb.
