This is more likely related to the Daily Activity not giving XP at all? You get a fake xp number and after getting real xp by hitting-blocks/crafitng in machinery the old “real” value is compared to what you should have now, since you didn’t get xp in the first place you “gain” -(daily-activity) + (real-crafting-xp), the first thing is a really big number the second not so much… so this is hard to see? Maybe this only happens with the Daily Activity? Hard to verify since the Daily Experince numbers are not achievable.
Go through portal to the character’s beacon on Munteen
Things go wrong
EDIT: I think it happened again just now. It looks like the daily XP bonus is overwriting the XP from machines when entering the world from the Sanctum. I got two thousand and something from machines and 547 from daily - but they started on the same point on the bar - with the 547 clearly afterwards. I did not record numbers before and after so not sure - will have a look again tomorrow - I think I know what to look for now.
We should have fixes for the negative XP and the repeated objectives /feats soon.
Going back to the issue where you said your light disappeared after going through a portal, could you clarify this a bit more? Did you mean the torch flame wasn’t rendering at all, or that the torch wasn’t lighting up surrounding areas?
