I cleared those rows of tiles the day the campaign started. Like you, I like to start at an edge and work my way methodically along, so yes, I’ve visited those tiles and no, I didn’t see any reason to drop any tags there.
When working on a map, that I’ve not yet completed, I’ve never noticed it in the past taking me back to already explored tiles like that, when there are still so many unexplored.
So, going back to @Helen’s original quandary…
… I’m wondering, if it’s because other people have come along since I was there and dropped tags, so now the TN software wants me to go back to re-examine my decision.
I still can’t see anything worth tagging on those tiles and those I dropped to test this I’ve since deleted.
Now going back to @Oli’s similar quandary in another post
Another reason why you will be seeing incorrect tags;…
…that will be because some people will be dragging the map around the screen with their mouse, whilst still having the last tag they used switched on and will inadvertently drop a tag when they release the mouse button! I only know this because I did it myself, when I first started here on a much older campaign, not realising that I was accidentally dropping tags in the process. When I did realise what I’d been doing, I did manage to go back and delete them because on that particular campaign they were blatantly obvious and I’ve since then learnt my lesson And remember, a tag doesn’t have to be dropped in the exact same spot for it to be included in the consensus, it’s within a certain radius and the size of that is depending on which tag was used.
There is a delay with that sort of thing I believe, whilst the servers do their recalulations. So if you’re testing your theories with tags, dropping and deleting various ones repeatedly, it will take time for the servers to catch up. You’d be best going away and doing something elsewhere then coming back to it later.
(I remember on past poly drawing campaigns, when you deleted a poly it didn’t disappear immediately, it might have changed colour, I can’t remember now, but it would eventually go)
