1.13 update (2.9.8 and 2.9.9) Backup any data before updating, previous versions shouldn't be effected, but still be cautious.
Send any errors to me and will be fixed asap
After updating to 1.13 do the command "/bank fix items" to convert old items to the new ones.
Small changes:
Better print to console on fixing uuids to usernames on /bank fix uuids
Added Money.No_Format to config.yml to not formal any money with millions etc
