Zypper stopped when it went into hibernation

I was installing Libre via zypper in my bash terminal. It was busy installing 333 packages so it to carry on on its own. When I went back to my computer it had gone into hibernation & my installation has stalled. The last 3 line on my cli is

 Retrieving: libreoffice-branding-upstream-4.1.5.3-17.1.noarch.rpm ...............................................................................................[done (10.0 KiB/s)] Retrieving package libreoffice-l10n-ko-4.1.5.3-17.1.noarch                                                                                 (233/333), 489.1 KiB (  2.5 MiB unpacked Retrieving: libreoffice-l10n-ko-4.1.5.3-17.1.noarch.rpm ------------------------------------------------------------------------------------------------------------------[starting] 

Is there a way to restart the installation without having to re download all the packages?

Unless you have disabled delta rpm and enable package caching then yes, otherwise i don’t see how zypper will be able to install the package(s) without downloading it first.
