No Zeta since two weeks from Zeta Ship Challenge!

In my first 3 months of unlocking the Zeta challenge I got none. Since then the rate picked up and I'm now averaging about 1 per challenge day. To answer your question, you're quite unlucky.

Same has happened to me. Just have to chalk it up as a loss and usually the numbers later will work their way out to you getting more Zetas than normal for a couple weeks down the road.

I went 4 months without one from them, I know others have had similar RNG slaps.
Buy them from the ship store is best way to get them tbh

It seems to run pretty hot and cold. Came off a really hot streak and haven't seen any for a while. But have had good runs too.

3 months with zero mats? Four? That's like 0/120. I don't believe that at all.

I've gone 0/6. I've gone 2/12. That's about the worst. I've also gone 5/4 and 8/12.

moved to correct sub.

yes it happens, just how the drops are on those.

Going four months without a single zeta???

I wish I hadn't opened my mouth (fingers) now I've probably cursed myself.

Happened to me too. Hopefully this post will help get the jinx off :)

On the other hand I've recently switched to buying zetas, so I can handle it.

I can't believe I said that too!

Yeah had to start buying them too because when i unlocked it 1 to 3 every two sims then after the thanksgiving update i haven't received but 1 or 2 so you have to sacrifice ships just to grow your characters i mean if they just guaranteed 1 a sim it would still take a month and a half i hope they can do better with this to many zeta abilities that would take decades to get them all
