I’m solving this thread. It was caused simply because I overlooked a while loop. What was a while loop should’ve simply been an if statement. Basically it was looping as long as poll was invalid, which if the connection is dropped (such as the case during an upload task to change from one checkin to another element) would cause it to loop repeatedly forever because the array no longer existed.
This should now be solved and I’m sorry. Version 4264.
