On 1.20.1 I found some defects when looking through the config, Fix Nether Portal Nausea, No Night Vision Flashing stays the same brightness if you are given night vision again when it is going away (subtle effects has recently added this to their mod as well I do not know if it will mean much to you), Show Bee Count did not work for me or at least nothing showed for me (both settings, I can test again), Alt Absorption Sound, Fullres Banner Shields is just a blob of texture, Long Level Up Sound At 30, Furnace Minecart Accepts Any Fuel, Crunchy Cake, Anvil No Level Limit, Deja Void would get me stuck in place, the void fog will stay if you go back up (havent tried this in a while) and the void particles show in superflat above the ground. I know this is alot but I felt it was necessary to report these issues. I can send the modpack if necessary.

the void fog and deja void things probably got fixed.
and a lot of these forgery defects are probably known.

most of the time i don't fix forgery defects unless their critical.
i do fell somewhat bad about this considering where the userbase is, me n una have talked about re-doing forgery but frankly no one has the time.

if you can confirm any in these in fabrication i'll fix them there. (just because it takes a lot more time to fix a forgery bug then it does a fabrication one, atm)
