One of the most useful plugins to have. Installing it I had an issue that was 100% my fault and wooly still helped me threw the problem and we got it working. Great plugin and Great dev is 5 stars in my book.
This plugin does what it says it does very well with the use of a MySQL or MariaDB backend. Has already solved our buffer overflow issues from the sheer amount of engrams we have increasing player data file sizes. With of course the added bonus of death item recovery and more slot space than ark data.
