Other mods involved: Unknown.

Link to crash report (if applicable): No crash report, but I can give both the latest.log and debug.log if required.

Most of this should be eliminated in the 4.2.0 release. Unfortunately there's still a small amount because of the size of some of the structures, as long as this doesn't happen too much and the world loads ok it won't be a problem.
