Help with Assert Errors

[Ylisse]

Could anyone help with where to look to fix any these assert errors?
I know it's explaining what's happening to each, not sure why in some cases but I'm unsure what files to look into with these particular errors to stop them popping up.

(Edit: The errors appear in Zones)
