some of the chapters ending half way really hurt the flow, but at least it's not like "From Overshadowed to Overpowered: Second Reincarnation of a Talentless Sage" who's chapter is split in to up to 6 partsThere’s also the matter of if the group is more comfortable in releasing things as soon as the material is available and they finish the job... or hold back the package to wait for whole chapter.
But split chapter is almost always the publisher’s fault.
The manga is originally monthly, but the publisher want to do biweekly update in the website, so they split it in half.
