Well, Amanda quit yesterday after no showing work (and removed me from Facebook), so it's pretty evident that she won't be coming in anymore. Since I'm now the only person working nights (except part-time guy, who is also thinking about quitting), my supervisor has informed me that I will be getting one day off a week (Saturday). My hours will be 10PM-8AM Monday-Friday, and a 12 hour shift on Sundays.
This puts D&D into serious question, because I'm not sure if I can host on my only day off. I will be greatly fatigued mentally after 62 hours worth of work each week. I will keep everyone updated on the situation.
