So I went off and bought a complete set of +4 implants for a cool 70 million, even the Charisma one because what the hell, it was cheap. I then jumped into my spare clone with no implants, flew him to HQ, and went to plug the new shiny +4s into my skull.
Error: You need Cybernetics trained to IV to use this item.CRAP! I forgot about that. So I put the skill on and saw it would take a couple days to train up and I had another 23 hours before I could get back into my +3 clone. End result, I've ended up adding about a day and a few hours to my end date for Caldari Cruiser V. DOH!
At least I will benefit from the +4s going forward once they are plugged in. Sigh.
