Btw I didn’t allow the texture pack, I just joined and got that message alert (Any funct…. read my reply above to see it) and I got 2 options proceed and disconnect. So I pressed proceed. I may have gotten it because I was on an MMO RPG server that has a server resource pack and I left then joined the shady server thus resulting in a bug that somehow showed the message.
Also everytime a server wants me to use its resource pack it asks me, and when I do accept it, the mojang loading screen appears and loads the pack. But nothing of these I just said happened, so probably just a bug and I thought the shady server had a resource pack.
It’s good to mention that above the message I got, it said “Server resource pack couldn’t be applied” (I just realized that)
If it isn’t a bug, then might’ve been a failed attempt of the owner inserting the malware into the resource pack, which made the game decline the pack since it only reads specific files used for resource packs.
