Strange @steem undelegate happening all over steem affecting reputation reset to 25 for allmost all users

Hi Steemians,

Either @steem is going crazy or some hacking or other thing going on.

Almost all accounts have been undelegated by @steem and thus resetting their reputation to 25 as shown in Steemd.com/@username where username is the username of any steemit user.

When you visit steemit.com/@username it shows the old reputation, but when you visit steemit.com/@username/transfers (i.e. your wallet) it then shows 25 as reputation.

Hope any of you have some insights on this.

This has really upset me and I am feeling demotivated now.
