Thank you very much. It was very helpful. However, I still didn't get my SP back, although the undelegation was shown on steemd.com and also it disappeared from minnowsupport project delegation.

Let me know please if you see my comment and you have an answer to it.

Never mind that! I found the answer in your post (i didn't read it to the end the first time :P)

Many thanks again :)
