Error in model information window -

[AnthonyC]

hey, i get this weird message in my Creo. i have no idea what caused it and i have no idea how to search for the feature which causes the 'break'

also my model tree is half grayed out and i have no idea why. does anyone know the cause? 

i have little experience with Creo and my company has very little technical support so forgive me if theres no enough information.

i have solved it. i changed my column tree to show feature id and then followed the numbers. 

somehow a part got moved into a group which then cause creo to have a fit and complain endlessly. it is resolved.
