Recently on my SMP server running 2.1.4 i have noticed this message popping up in the console, it is not causing a crash but it concerns me. Does anyone have any thoughts? i tried rolling back before the first instance of the error i could find in the log, but no luck. Related issues i found from other FTB packs lead me to believe its the begging of some world file corruption, but i cannot confirm as the issue/circumstances are not identical.
Loading pulling the world onto my local machine and running in single player does not seem to have the issue, so im really unsure what the cause could be.
Edit: Also if the dev for the aroma backup reads this thread, any chance you can friendly it up a bit for linux? Right now your intended directory structure is not compatible with linux, i would be more than happy to help test a new revision before release.
