On the Biology proposal on Area 51 I noticed two recently committed users with exactly 151 reputation. This is a bit unusual, as when you have enough reputation to get the account association bonus you should have enough reputation to have your other accounts displayed on Area 51 and counted for your total reputation.
Now, I remember the completion percentage of the proposal from yesterday and I'm pretty sure it didn't increase today, so these two users who should be counted as experienced SE users (with >200 reputation) didn't increase the committment score. So this might be not only a display bug, but it could affect the proposal score. Though it might just be that the committment score is only updated once a day and this is just caching.
