Thing is that they don’t really have time to do so. There’s a risk of an overflow from that dungeon and they need competent parties to investigate to make sure there won’t be one. Clover has distinguished themselves by beating that one boss and showing that they have enough power to win against an enemy that not many can beat
Also not sure where you’re getting that it was a normal feat for an adventure. Them beating it is the main reason why they’re even allowed to participate and also because the noble knows who the MCs master is. These two factors are why they’re in the dungeon. If it wasn’t for those then Clover wouldn’t be allowed to participate.
As for magnets for bad luck I dunno about that. They really only had one enemy they’ve met that they shouldn’t have. Can you elaborate on why you think others should view them as magnets for catastrophe?
That's because they were not properly rewarded. They only were rewarded because the enemy was strong and they can beat it. If this is is indeed abnormal feat, they would've been rewarded with instant promotion (I still don't know how they conduct a normal promotion). That's why I am fine with the incident in the jungle.
But the incident with shadow stalker and the orcs were only rewarded because there was noble who noticed them. They still don't get promoted though even though it was A-rank monster that haven't appeared in 10 years. And the guild actually mentioned how helpful it was because there was no record about shadow. That reward is shitty like it's just a normal achievable feat.
As for the magnet of disaster should be obvious enough after they discovered abnormal occurence on the first floor when the others A rank couldn't found that how many time they explored. At this point, the mc's party should've been stopped from dungeon activity and received a training because they were prone to met another abnormalities. 3 abnormalities in a row is no joke considering there is no report about other parts in the country. I know they were strong for a rookie but the other A-rank party still got better reputation than them. There is a choice to trading knowledge and experience between A-rank party but the author chose to retiring them instead because of that verbal incident. Wtf
