[Bug Report] Stat don't stick for logged off players until restart

[InsideBSITheSecond]

Hi and tanks for making this project.
I have a (maybe stupid) question
This happens when I log off:
If I reboot the mc server stats are going back to normal. But until I do restart, a logged off player's progress doesn't seems to stick in the prometheus metrics. it just reports the stat as it was before the player logged in.
(rebooted the server at 6:01)

is this normal or am I stupid ?

I do have the same issue on my PaperMC server (1.21.4)

After watching quickly at the code, it seems that:

• if a player is online, it uses Bukkit stats (which are realtime, but only works if online)
• if a player is disconnected, it falls back to stats from the map JSON (which is not refreshed until a map is fully saved I guess?)

We would need to keep the previous value in case a player disconnect, without a fallback to the saved value
