OFFICIAL Facilities and Facility Manager

[Sundos]

"The key point is that you will be able to work ALL your friends facilities after 8 hours has passed since the LAST facilities you worked."

But sometimes (most) I cannot work others facilities for at least 12 hours.. and many times like today I cannot REwork their facilities and yet it has been OVER 12 hours.. and 2 days I retried 2 peoples facilites 5 times in 24 hours and FINALLY I could REwork their facility.. SO WHAT AM I DOING WRONG?
