Game crashes when saving & other log events

Hello,

Sometimes the game crashes to desktop just after saving. It did so right now. I didn't get the option now to send the crash report because the game client crashes completely, so I thought I'd share the info here:

It begins with a repeated set of events like this:

[03:13:57.879] [1] [WARNING] Failed to Unsubscribe event handler: STATIC.Void <OnSelectDelegate>m__0(StationaryChoreRangeVisualizer, System.Object)
Not subscribed to event
[03:13:57.879] [1] [WARNING] Failed to Unsubscribe event handler: STATIC.Void <OnRotatedDelegate>m__1(StationaryChoreRangeVisualizer, System.Object)
Not subscribed to event

And then:

[03:16:58.431] [1] [INFO] Deleting old autosave: C:\Users\xxx\Documents\Klei\OxygenNotIncluded\save_files/auto_save\A new world awaits Cycle 605.sav

Also, there are LOTS of notices like this in the output_log. What does this mean?

[02:28:43.544] [6] [WARNING] Effective mass cannot be greater than capacity!
[02:28:44.544] [6] [WARNING] Effective mass cannot be greater than capacity!

Also these I have thousands in the log, these happen only when the rock crusher is enabled:

[22:30:43.256] [1] [WARNING] RockCrusherComplete RockCrusherComplete (UnityEngine.GameObject) has material needs cached, but no open fetches. materialNeedCache=1, fetchListList=0
[22:30:44.256] [1] [WARNING] RockCrusherComplete RockCrusherComplete (UnityEngine.GameObject) has material needs cached, but no open fetches. materialNeedCache=1, fetchListList=0

These I haven't seen much, but today there are some. Don't know what that means.
