Regarding the Memory Fragments order of acquisition

Hi guys,

A quick question regarding the memory fragments.

I spawn an Elder Guardian on a Tier11 map with a memory fragment and Elder himself on a Tier10 map with a memory fragment also.

I did the Guardian fight first and get the fragment, but the fragment (and the orb as a consequence) was downgrated to TierV (cause I only have fragments I to IV).
Also the memory fragment from the Elder map (blue circle on Tier10) was disapear.

My question is, from now on memory fragments won't spawn on Tier10 maps (cause I already shaped a Tier5 map), but a Tier11 map will again be able to spawn a memory fragment, so I can get a TierVI shaper orb and continue shaping my Atlas?

Is that correct?

(I made a quick search but the informations I gather were a bit misleading around this matter)

Any help will be much appreciated.

Correct.

I did a similar thing this league. IIRC, I ended up getting fragments I, II, and III all from T8 maps.

Thanks man,

Much appreciated the clarification.
