You might have had unlucky enough timing to find a short lived bug. Try:
./daily.sh
lnms db:seed --force
lnms user:add newadmin -r admin
log in to the webui and add roles back to users missing roles under <gear>->Manage Users
Some users may only need lnms db:seed --class='Database\Seeders\RolesSeeder' and lnms tinker --execute='Bouncer::refresh()'
