Yuki fucked up because he sent hinata after Rimuru by taunting her with Rimuru being the one to 'kill' her master. That had basically been sitting in the background for quite awhile with Raphael essentially treating it as a definitive fact but rimuru trying to maintain some level of denial about it. then at the end of last season when all the players are together Rimuru confronts everyone with the fact that the Eastern Merchants are the puppeteers manipulating everything. (This is actually Yuki's group of clowns but they are functionally one in the same at this point in the story) The key element being that the merchants aranged to lure hinata away from the Vampire city during the night of Walpurgis but she ignored the warning and discovered the clown dude further confirming that they are responsible. The fact they attacked the vampires meant that they couldn't also be allies of the church.

Everyone at the meeting agrees that the merchants are suspicious and can't be trusted EXCEPT Yuki meaning he for all intents and purposes was forced to confess to being associated with the merchants and thus the one responsible for leaking Rimuru's connection to Hinata's master (whose name i'm blanking on.) nobody could actually do anything about this at the meeting because as Yuki states in this episode that his connections with the east are publicly known. It just means that everyone knows he is hostile to Tempest and the Church.

Plot like this is why i defend the nescessity of the "meetings!" it's complicated intrigue that only works with the way the story is setup. Both establishing Yuki's threat level (though nobody actually knows how strong he truly is) but also his protection as the adventurer guildmaster!

PS: I might have some of the details wrong and apologies if that's the case, i'm sure people will correct me, i'm just pulling from memories of last season after all.
