Ok, I have updated the node install script to build from master of the new repo. I also made the update command remove the existing code because it was re-using old compilation files.
Here is the command you can use to update your nodes (assumes logged in as root on your VPS):
cd vps && git pull && ./install.sh -p lasvegascoin -u
/usr/local/bin/lasvegascoin-cli -conf=/etc/masternodes/lasvegascoin_n1.conf stop
This new version has no corresponding release in github yet, but in future if you want to update to a specific tagged version (for example v3.0.5.1) the command would be:
cd vps && git pull && ./install.sh -p lasvegascoin -r "tags/v3.0.5.1" -u
