This feels like very much one of those cases where the group that was translating hadn't kept up-to-pace and only decided to prioritize a work as the result of someone else releasing chapters of it. Particularly as they posted the same exact part of ch 10 as the other did, rather than the entire one.
Not saying that is a bad thing though, just saying that I think that is what happened. Though what
can be considered a bad thing, I suppose, is that the fact they werent up-to-pace with the raws suggests they might have swamped themselves with more work than they have staff (alternatively time, if its a hobby thing) for.
Though it didn't sound as if they were so far behind that it would build up enough stress to actually become a bad thing, so I as such doubt its a health-hazard to them (although I suppose one could also consider it as a bad thing if they effectively "hog" popular manga, but
that is a topic destined to become drama, so I will stay clear of that. Particularly as I cba to look into what else they tl).
@moderateTrouble I think it sounds more like the "drama" is regarding ppl harassing one of their staff, caused by randos assuming they bullied the other tl away from the series, as it did not specify what was said to make it stop (the images suggests it was a pretty ok and courteous discussion imo).
Responding clearly and publicly (as it is randos) with proof (screenies) of what was said seems like the apt response imo, as protecting a friend from harassment should be a high priority.
