Thanks for the info and your upvote!

my node switched to rpc.buildteam.io and it stopped updating my SP

I don't know why but always when I make a post there are strange things happening around me :) Maybe it is a good sign...

Edit:
It seems to be a general problem with the Steem nodes. I also got some "transaction broadcast errors" today on Steemit.

BTW, upvoting this post by you lowered my amount quite a bit

That's correct and it should be as it is because you've voted me before. Maybe I will increase the maximum allowed upvotes for the same author a bit in the coming days. Your value is okay, not bad ;)
