I'm going to need some more details here:
- What version of Clusterio? Clusterio 2.0/Subspace Storage is still in alpha, and Clusterio 1.2 has been deprecated, so I'm not sure how supportable either of them currently are, but either way I'll need to know which one you're talking about before I can take a look.
- What do you have set for the Hourly Autosaves interval & prefix settings?
- What are you expecting to happen, and what actually happens?
