On my Minehut server, I'm using Undertale data packs from planet Minecraft from the creator SonicRushXII though the data packs work perfectly fine in single player, Minehut just wont register them, I was able to get one data pack to work, (X-Chara) it was after lots of trial and error and restarting of the server so I don't exactly remember how I did it, and stopping the server doesn't help either, I was thinking it might be a storage issue, as I'm using the free subscription so it only has 1GB but unless Minehut is taking 99% of that GB before I use it then I don't believe that's the problem. Any ideas anyone??
