every single guide before LB7 seems to not be working at the moment

Oh thank you so much, I missed that! It's fixed, and should be updated on the live page in a few minutes.

I downloaded the sprite sheet from pixel wars, and it's all blurry. Is there a clearer image available?

It seems our image hosting automatically compresses images, so here it is on a different host: https://i.imgur.com/5RP1uQn.png

Step 80 has changed from 16 assassins to 16 mixed assassins, sabers and lancers.

They are from 20-24 PDT which corresponds to 5-9 in my time, so people from CEST time zone must be either morning larks who don't have work at this time or night owls who can sleep during the day. They really could have thought more on timing when they just crammed entirety of Europe with NA and called it a day.

Yeah this really is unfortunate, it does not work very well for East Coast US well either, due to the late time window being pretty much from 1 - 3AM. It would have been nice if they rotated the times throughout the day a bit more so other regions would have more of an opportunity to run the quests, but in the end they seem to have strictly kept to the schedule equivalent to when it was JST > PST.

I finished the walkthrough, and "Mission 61: Defeat 9 [Neutral Alignment] Servants" did not clear. Did an additional run of "Free - Part Seven" to compensate afterward, if that helps.
