part of the problem is that since its an intermittent bug its difficult to provide a solid test case. however, my simplified script should reveal the bug after many iterations.
it may be necessary to run this code a couple of times to see the crash. i've had the same code run 800 iterations and then on the next run crash after 40.
oh, and i should explain what i mean by crash. the script is exited without an error. my logging has shown that this almost always happens on press or release of shoot_half. however, if i remove the shoot_full lines this no longer occurs.
i've also tried calling press("shoot_half") through the pcall method which calls functions and catches errors. it doesn't work.
