@Athedes - this is my understanding:
1. This manhwa has already been licensed in English. That's why updates were stopped on MD, but they continued on Sawateam's own website, so you can head there for more info if you want. But usually, once a series has been licensed, its rare for another group to pick it up - out of consideration for the author, and I assume because of legal stuff too.
2. Generally speaking, it's not always bad if a second group picks up a series. I think it's common courtesy for them to try and get an OK from the first group where possible, otherwise it would be considered "sniping" in most cases.
3. For this manhwa, Sawateam have said that they didn't mind another group working on this series. HOWEVER, it's veryyyyy bad to steal Sawateam's (or any other group's) translations and claim that they're your own. That's why chapters 35 and 36 were deleted.
I hope that answers your question.
