Obtaining Zerek modules

I saw with StarKiller Luke that they're available in the 1st success of the five 1st tiers of its event ...

But not in the two last tiers . . .

So even with the 7 tiers done, nowhere to find them ..?

For the level 135 (121 more precisely), need to have 250 for each toons ???????????
Today, I've got 210 with the StarLuke events ...
MJ, DY and SL are lvl 75, 7* (except SL 48/100, gonna 7*in 4 days now).

So 2 days with no toons progressions (except a pseudo Coliseum where you loose time to find the good team).

That's it mean, that nobody (F2P or not) can access level 135 at the end of the DJJ's era (or another one) ???????????

According to CG, when you change the era, your Zerek or what you've collected turn to credits and the few we got is not enough to leveling to 85 ...

I’m kinda curious myself since there are about 25 new 7 star level 85 Mara and Soda that just appeared yesterday on the leaderboards post being able to get Zerek.  No one should have access to them even if you use crystals to star level Mara and Soda during this week.  So either these players were sitting on them and just suddenly decided it’s a great time to level, CG pulled shenanigans and merged some era players together, or there’s a ton of cheaters and CG doesn’t care.  I’m also having trouble believing I’m having a hard time with tier 7 with era level 75 toons and level 66 loaned toons while quite a few players with era level 60 mains and level 56 loaned are in tier 8 and 9 Jotaz today.
