Thanks everyone. We'll keep checking into this!
@Winnower is this appearing in the UI as well? My theory is that Update 5 set it to 4,000,000 by accident but the UI still said 1,432,550, and now the UI has caught up with the error.Amazingly, even more is messed up than it was before - xp for vet levels has gone from 1,500,000 to 4,000,000.
This could explain why it's taking two to three times longer to level than it should be, and would explain this picture if 4,000,000 is the actual requirement.
This therefore seems like a bug in which 4,000,000 was actually implemented instead of 1,432,550, which explains the slower levelling, and is also consistent with the rate of slower levelling - 4,000,000 is 2.7 times 1,432,550, and reports say it's taking ~2.7 zones to rank up.
Note the numbers on the xp bar (grey bar under health bar) vs what the UI says.
That's because the grey bar is working out what I have as a percentage of total required, Wykkyd's shows I have 11% xp on my bar (which is what I would have if the xp needed was really 4 million to level)...so the grey bar calculates that percentage and tells me that in numbers, and you can see the progress on that bar vs what it was the previous day. The day before this I had 33% of my level with the same numbers...today I have 11%.
TL;DR: you guys have set required xp for one VR level to 4 million instead of 1.4 million.
