While working on a mod, I tried to edit the properties of one of my cells and it was greyed out. It had previously been available to edit, and I have no idea why I could not edit it. I saved, closed the CK, but still no luck. I looked online, could not find any posts about it. So, I made a duplicate of the cell and was able to edit the duplicate cell. At that point, I stopped looking for an answer, but the problem has reoccured. I've checked random cells to see if this is effecting all the cells, but it is not. The problem is not even limited to the cells I've modified either, having checked those and being able to change Edit properties.
Does anyone have any idea why this is happening?
Thanks
