@jabo38s: i hope you had you system running over night. After talking to Jaguar we concluded:
Try restarting the browser only and check if the confirmations still appear weired.
If that doesn't help restart ncc and check if it helps. Last try restarting nis and see if it helps.
I checked with my nis/ncc/gui and the confirmations for your transactions were ok.
Okay, the good news, I did leave my computer on and browser and node up all night running. I wanted to leave it just as it was just in case somebody had a suggestion.
I went to my computer and wanted to get screen shots each step exactly. I figured I would try to make it easy on everyone and make the screenshots each time end with 0s or 1s instead of different numbers and I would set the page in the same height. This meant I needed to wait. I positioned my page just the way I wanted it and and the jumbled block numbers exactly how I wanted them, but then I started sending some transaction and playing around with other buttons. I was checking incoming and outgoing and pending while I was waiting for the count to get to 0 (it was around 6). Then I started reading on the forum and I missed my count. More waiting and what not and finally I got to 0 again.
Next thing I know, the blocks aren't jumbled any more. They are now all in order exactly matching the block explorer.
To repeat. I did not close my browser, I did not restart my NIS or NCC or my computer. I just kept on using NEM and other websites and clicking in NEM on multiple various tabs and then there was a spontaneous block rearrangement to the correct order. (I am guessing this is a good thing, but sure confuses me)
[s]Per normal request, here are my logs. :-) [/s]
Now.... a little bit of extra information that may or may not help and/or may or may not be related. I haven't harvested a block since #5531 and usually I get them regularly (a couple per hour). I think this is related to the fact that I was playing around with remote harvesting. I tried to activate it a couple of days ago, then it took about a day to activate (where the remote harvesting was going, I don't know, I just entered my password). Then when remote harvesting was activated, I tried to deactivate it, again just by entering my password. And now I am still waiting a long time. I still see a message saying "deactivating remote harvesting". So I am not sure if this remote harvesting issue is related to the #6980 problem but it would be interesting to know if Amy and Makato also were experimenting with remote harvesting when they got the #6980 error.
