Is anybody else continually losing Exotic Matter for no apparent reason or am I missing something? So far I've lost 15k to 20k worth in the past couple of weeks alone

Have you been spending energy in missions like "Stellar Cartography", "Unstoppable Forces", "Stabilize a Wormhole", or "Exo-Rift Expansion"?

No, I haven't been spending energy on those missions. I will build up a few thousand exotic matter and then it just disappears and and I'm back to zero. It has happened no less than three time in the past week alone

Weird. Some buildings require exotic matter to build. Have you built any of those?

If not, try Contacting The Devs. They can look at your account, and if there is something wrong, they can refund everything you've lost.

It hasn't been from building. Just plainly disappearing. It happened once to my other resources but it seemed be an anomaly so I worked through it and ignored it. But now its happened a number of times with the exotic, but not with the other special goods like complex parts.

Contact the devs like I suggested then. My link above takes you to a forum post where Dan explains exactly how to do it. Don't send him a PM; follow those instructions to do it properly.

someone is logging onto your account and sending the EM to themselves...i would do it if i could

Ok are you guys ready for this... this happened to me and another legion member at the same time last night. Our Artifact points appear to have self converted. I lost almost all my arti points right down to 80 left. Yet I gained a whole shwack of artifacts. When I noticed, I mentioned it to the others and sure enough it did happen to atleast one other person.

Wow, now it actually sounds like Milbrandt is right. Definitely go with Matress's advice.
