Wet molt on a sick tarantula in ICU?

I have a Chilean beauty which wasn't eating and seemed weak and dehydrated. So I put her in a plastic container with damp paper towels. I check on her a few days later and she has recently molted. Legs look great but the old abdomen is wet and partly still attached. Did this happen due to the high humidity of the ICU? Should I put her in a dryer cage? She still looks weak, and her legs are held close to her body. She is still young about three in long. Any advice?
