I don't think any of the other Lemmy apps are showing a total score. It doesn't work in Connect regardless. My score was approaching 250 (showed close to 400 viewing from another instance). If you delete posts or comments it really goes off. Current score is less than 30. My account on another instance shows zero. Not sure if there's any value in showing this number as it is quite inaccurate.
In Connect I see your points as 112 currently, from you user page. I think my points total is correct too and haven't noticed a problem. Have you tried logging out and then back in on Connect to see if a refresh does anything?
It's been doing strange things. I have tried what you suggested and several other things. I think it has more to do with deleting posts/comments than anything. Deleting drops many more points than exist in the item to begin with. Try creating a post and then delete it. It would be nice to see it's not only me for sure.
Huh. I was at 107. Deleted a 9 point comment and I'm at 57. Now I wonder if there's something I can do or it has to be fixed in the code somewhere.
EDIT: I wonder if other people see my correct total and it's just messed on my end.
EDIT2: In the grand scheme of things, for me at least, this issue isn't that important since I don't care about the points total that much and eventually this will probably get fixed.
If I cared about it that much I wouldn't have deleted another (single point) comment. I'm now at 4. What I've been saying is if it's going to be there it should be accurate. Otherwise, why display it.
I'm not sure the dev was aware of this issue. Many on here were from Reddit and used to having a total so I think some find the feature useful. In certain instances it's not accurate at the moment but the dev has been just getting updates like crazy so my guess is this will be fixed in the near future. Unless it's more entangled with how Lemmy/Kbin works and a code update needs to happen there.
