Retroactively generating features causes server to loop while loading

Morpheus1101 · May 21, 2014

I have just updated to the latest version of AOTB and each time the server gets to "Retroactively generating features" ... various entity ID's from whats existing or meant to exist it throws an error an starts the process of loading various things in the chunks all over again.
