I resolved this problem by adding a few seconds of sleep after creating a list and populating it. The problem did not appear when I first tested my code, but it was morning European time and Twitter may not have been too busy.
In the process of finding this out, I seem to have created some corrupt lists that cannot be edited or deleted. May I ask someone from Twitter to kindly contact me to help get these lists removed from my account! Thanks!
