I had the same issue (influence 50 Temple so was quite upset). I used the 'Companion Locator Terminal' on Odessen to get her back. Customisation and influence were restored. It is showing her as a duplicate and I can summon either.

I don't think this is just an issue with EV/KP. Rav/ToS are significantly harder than other veteran operations. Most will avoid them when gearing up in favour of the easier ops. Then when they progress through them there will be no reward. With galactic command Bioware have been encouraging players to do all content by giving reward roughly equal reward for the time spent and the difficulty. I think that is a good thing and should continue. With the current distribution that would not be the case. Discourage players from farming EV/KP, will only move them to farm TfB, etc. It would be better to encourage them to play all operations.

I agree with this statement. One of the issues is reward in operations. If you can get a full set of gear from EV/KP then what is the incentive to do the harder operations? For example, my guild was progressing through Rav HM in 4.0. I remember the first time we took down Torque. It dropped an earpiece. No one needed that earpiece because we all had gotten it from EV/KP. The only thing we could do with it was random it out and whoever won it sell it to a vendor for a few credits. It felt like more of a slap in the face rather than a reward. We basically gave up progression raiding at some point as most of the group preferred getting rewards from doing easy content than the constant wiping leading to getting the next boss down. We used to have both. How about another approach: Each operation boss still drops 1-2 pieces, but an operation only rewards 1-2 types of gear. E.g. EV first 4 bosses drop implants and Soa 2 earpieces. KP first 4 bosses drop relics and Karagga 2 offhands. This should encourage everyone to play all operations instead of just EV/KP and still give great rewards for those progressing through any of the operations. It has other benefits: If you want a specific piece you have a way higher chance of getting it by targeting an operation that drops it. Avoids the issue where the only piece you want is on the first boss. You lose out on the /roll and have no other loot to look forward to for the rest of the operation. With my example it is also a bit more alt friendly IMO. You can run EV/KP to gear alts for the non-legacy transferable pieces (other pieces can be gotten by your main and transferred in legacy gear).
