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?

We reloaded the plugin many times in this process. It was one method we used to force in-game memory/RAM to dump out it's cached version of all of the players data json updates.  Apparently running /st -> gain prestige also does this for that specific player as well.  But no, we didn't see reloading the plugin after someone prestiged up that this fixed anything.  The XP for that person was still stuck.  No idea why.  We ended up just taking that other servers config/SkillTree.json file and loading it onto the broken server and reloading.  That fixed it.  Hence we were wondering which of the settings above that are different might be the cause.  No big deal now, but at least if anyone else complains or sees this, it might help with that debug.  

None of those settings would impact at all.

Unless the xp gain mods are so low that it wont register the xp being given to the player, but I have no idea what the context of these are.
