Bad Indian moult- any advice?

[Tiscandy]

Hi all!
Yesterday one of my Indians was running around the viv with the remains of a moult stuck to her abdomen. I peeled it off with the help of a damp paintbrush, but now the tip of her abdomen is all brown, and there is a strange green lump on the underside. This lump is wet to the touch, and leaves a trail of green goo as the stick moves.
The stick seems frisky enough- at the mo have her in solitary confinement just in case.

Does anyone know what the problem could be and if it is serious?

Thanks,

Hi, I don't have a lot of experience with stick insects but I have raised praying mantises and have seen this before after my mantises shed. If it is the same thing it should go away in a couple of days. Hope this helps! :)
