So 141k dropped meaning cycled, has to be. So can you confirm if you dropped 21692 drops all with D-class amp? I do doubt it.
If you're keeping track of your last location ingame and you're seeing your avatar has moved back, but why is that an issue here?
Do you think the latency is creating pockets where your peds are just going into a VOID in the system? Possible yes, but unlikely.
Perhaps the server didn't save your last known coordinates due to server lag, however, that doesn't mean the system isn't registering your decay especially if you are seeing, the respond vector on your finder, otherwise you'd have claims that would stack as it registers on server.
