Au Survival command game crash

Looking back through the logs you had connection issues.

Kicking shieldzee1 (Steam Status "InvalidAuthSession")

This is common when the node you are connected to via steam may be under going maintenance. It will appear fine but when a higher data rate between client and server become present then it may drop you, in this case when you used those commands. There are other reasons this may happen but from my experience this is most common.

A fix I have found that works is restarting your PC, this hopfully will force steam to connect you to another node. If that does not work just a quick router reboot will do the trick. If you have done both of them and still experience the kicks for the same reason then you may want verify game files.
 

Hope this is sorted now.
