XP locking up after 'gain prestige'

On one of our servers, the XP is locking up for everyone once they gain prestige.  I reproduced and did everything I could think of to fix the issue.  We are using the latest SkillTree version (1.6.5) you released last Thursday.   I tried resetdata at first and that seemed to unlock the XP but of course that starts them out with no prestige and back at lvl 0.  XP at that point works fine.  I would then givexp enough for them to use /st -> gain prestige, and after going up in prestige, the XP locks out again.  Meaning they/we cannot get XP points to accumulate in game.  It's simply stuck at 0.  The odd thing is that our other server works just fine.  Any ideas or ways you can help us debug this will be appreciated.  Prestige is a major feature on our servers, so folks are clearly disappointed this isn't working, LOL.  Thank you. 

We managed to get this working again by plugging in the config json from our other server.  There are literally only three deltas that we found between the two, but looking at them we are still clueless why these differences caused the XP to lock up after each prestige gain.  Hopefully that print is not too small to see.  Maybe the Wipe XP None vs Refund?  No idea.  The working json is on the left.  The broken one on the right. 

That is really strange. I assume you reloaded the plugin after getting prestige, but before adding the config from your other server?
