Feature for consideration: log/save previous/new seed numbers so we can go back in an emergency or if players liked a previous map.

@YouMustNot commented on GitHub (Jun 4, 2020):

there is a workaround:
put this into command_wipe.sh

newseed=$((1 + RANDOM*RANDOM % 2147483647))
sed -i -e ‘17c\seed="’"$newseed"’"’ /home/rustserver/lgsm/config-lgsm/rustserver/rustserver.cfg

just remove the seed section from your rustserver.cfg.
this script will add a new random seed then update to a new random seed when you ./rustserver wipe.

updating LGSM may overwrite this workaround so be aware of that.
