Thanks for the reply.
I suppose if the nodes had issued the block but didn't communicate with each other 100%, but that sounds like the beginning of a fork and the nodes are catching it just in time. I am not saying there IS a fork, the explorer is 100% ok other than that, in respect that we are all mining on the same block and the explorer reflects it. I found another instance of it just a few more blocks down the line. Might want to look into it.

Actually, there may have been a minor bug introduced when the block time was changed to 30 seconds during the first fork. I think that this parameter adjustment is being done more correctly now with the switch to 2 minute block time in the upcoming fork, and this issue should resolve itself.
