some thoughts - maybe she's feeling a bit insecure without her crate? is there room to put it in the kitchen with her and cover it with a blanket so she has a dark safe space with the door open?
or, as she is 8 months old she may be starting to come into season, which could be upsetting her routines if she's feeling a bit uncomfortable in the nether regions
Pearl did exactly the same in the lead up to her first season although this may not be the case with Poppy of course
