Pixiv versions are also up. They have better tagging (making it easier for 'translated' tag suggestions) and clearer formatting of commentaries (making it easier for commentary TLs). The Pixiv versions of the latter "sketch" versions of this comic series also hint at where to find the fully drawn and shaded versions of the comic (fanbox rewards, digital book releases).
The Twitter versions does have the >100 day daily updated manga challenge counter going on though, which is absent from the Pixivs.
That said, both the Twitter and Pixiv versions are image dupes of each other (at least from the handful of images I checked), so now that these Twitter versions are upped, the Pixiv versions of these already uploaded images should no longer be uploaded.
