I have an open issue #204 , and I figured out somewhat of a fix. Users will all need to sync to stop this freeze from occuring, is there a way to add an "AUTOSYNC" to the server code to force players all to sync their time? it could be on a timer set by the serversettings.txt and would prevent lag, and all the load issues plaguing us. Thanks!

Subspaces has nothing to do with feezing - The freezing may have been resolved in 559f7de

If you want to try dev, it's on my build server http://godarklight.info.tm/dmp/ and DMPUpdater-development
