[YouMustNot]

OS: Ubuntu server 18.04

I have a rust server well 4, none of which will generate a random seed is I leave seed to “” I just gens the same map over and over.
./rustserver wipe and ./rustserver wipeall does not change the map seed

Note: this has never worked properly.

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]

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.
