Can't finish Trauma Code of Characters by 100% [2]

Hi guys, good day! Just want to know if you experience this or not but I can't finish the trauma code on 100% (except for Haru) I don't know why but when I go back for the last episode/chapter of the story I can't select the other choice for the different branch of the story. Can you guys give me some advice or am i just dumb for forgetting something 😅

Rescue Rolls [4]

Was rolling for narja. Had 17 until guaranteed narja, rolled for 10. I got yuki, nothing wrong with that specifically but now I have 69 more rolls until guaranteed narja (mind you I do already have yuki). It would **** if this happened again. And I would prefer not to blow large amounts money attempting to pull. Did this work as intended and I'm just stupid or did something go wrong there?

Did not get the survey in my mail =( [2]

Hi, I'm a global player and didn't get the survey announced in the narja reveal stream in my email. Did I miss anything (or did I delete it by accident?)

Does Replica Core works if It's another combatant who draw the card? [2]

Example: - Renoa equipped with replica core - My nia draw her attack card Would the buff activate? or does it only work when the equipper draw themself?

Curious [1]

Hi, I'm having some cards with Retain:Change this card to... + Draw 1 Of course, If I play this right now I'll get a draw But when It has been retained to be another card, I don't get that draw. Is that bug or just my imagination?

Sereniel and Peko Ego advice wanted [4]

I understand that its a seasonal character, but should I only really bother getting her ego to level 2? The potential 50% damage should only only be needed for players going for future high scores, right? Should I bother levelling up Peko's ego? Or save the resources

Lab 0 Forbidden Spawn achievement [2]

I want to get this achievement. I know i have to attack this guy, but ever since the update, when I get this event, it doesn't let me attack and can only choose the 2 fates. Did they replaced it? or am I just unlucky.

How do you Get a Diff. 6 (Lv 51+) Codex? [2]

I've cleared a Diff 6 Chaos and the Lv70 ones in the seasonal Chaos, but I only get Diff 5 (< Lv 51) codex. How do I clear the initial Lv 51+ codex to unlock higher difficulties?

Stat requirement in last potential ? [3]

is there confirmation from dev if stat requirement from last potential must be only raw stat appear in combatant front screen or equipment from save data also affect it ? I try switching between default 15k and other save data, but the stat number doesnt change, and I dont know if that last potential bonus is activated or not. I tried searching answers in CZN official discord, but some people said both side type of answers (raw stat and include equipment stat). especially orlea 800 attack and khalipe 700 attack.I need sacrifice their best main stat from memory fragment, to activate those bonus.

Is the faint memory feature problematic? [3]

The first card removed is basic card. remove card in the game instructions was "0".. correct? why is it now "20"? This does not match the instructions in the game.
