Help with Central Zone's Guardian quest...

[RhymeBomb]

I have three power cores. There is no way in hell I'm gonna check every container on this planet again for the one I missed. I'm the guy that meticulously checks everything in sight, so how I missed this one...

 

Thank you for any assistance.

Ask maintainance droid for help.

Where did you find the three cores you have?

[Hassat Hunter]

There are far more than 4 cores on the planet, so it's not a "4 out of 4" deal.

Also, try asking around. Some droids might be able to help you get more if you haven't found them all during your travels.
