Server crash while trying to save statistics.

The server is crashing because I am removing some of the biomes, ill need to remove the auto-save feature for statistics.

Code:

[13:32:44 WARN]: Couldn't save statistic TranslatableComponent{key='achievement.
exploreAllBiomes', args=[], siblings=[], style=Style{hasParent=false, color=º5,
bold=null, italic=null, underlined=null, obfuscated=null, clickEvent=null, hover

ull, italic=null, underlined=null, obfuscated=null, clickEvent=null, hoverEvent=
null}}'}}}: error serializing progress

Help?

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

I'm getting this too - it's really weird.

 

Does anyone have any clues?

 

Also I'm only adding mob spawns to biomes and I'm getting that error thrown. No crashes though. Bump?

 

THIS IS MY PROBLEM, TOO! LOOK AT THE FORUMS EXCEPT IT'S LIKE THIS--
