Totally agree with Baggos. As we are not all the same on this planet, the better option is to try making something by yourself at start, as there are a lot of free datapacks out here. This is the only way to find what is working or not and make a dp based on your own style and ideas. If you want something preconfiged, you can easily find a free one as there are a couple of websites with custom modifications depends on what you were looking. As for bugs Baggos already told you the truth. There isnt an actual 100% fixed datapack
