In my case, I did something that many have probably done: install the latest HF patch on the latest BR (Full Game) available to date. Of course, there are a few details I want to clarify, due to the time difference between the two releases. I thought it was a good idea; the BR has been on the same version for quite some time, while the HF patch just released its latest update last month. I also want to add that to do this, you must be very careful with the Sideloader Modpack section. The HF doesn't include all the packages, but I do recommend moving the Sideloader Modpack mods you're going to install to another location. (I say this to avoid duplicates in these folders, as there are often conflicts when trying to load the same zipmod with different versions; sometimes I think it even loads randomly. That's why, to avoid this, you have to read carefully when you get to the window for the additions you want to install).
I'm not currently having any problems, although I have noticed that several of my zipmods are corrupted. These are my own downloaded mods, not the ones included with the Sideloader Modpack or the HF Patch itself.
You can see this in the output_log.txt file and on the Koikatsu Discord bot.
