Milestone completion assignments missing

In the milestone assessments I completed 4/10 but had not claimed them, so they was removed the following day this what it looks like now as I finish the 6 that was left to make sure they did not get removed!

the question is this has they been a new rule if don’t claim the assessments when they are completed they get removed after a certain time and lost of the points too?  Mine want missing the following day so that was big lost on my score so I now trying not to be demoted. It was about 50k lost points that not happy about, I was going to quit SimCity till I found one of other I know also lost say lost over 80k last week as she had not claimed! 

is there a new rule if don’t claimed the completed tasks they get removed after a certain time?
