We fixed the weirdness with trying to add points while drinking the Draught of Reconfiguration. Now you should be able to add points just fine and your options won’t be greyed out.
Fixed in Patch 1.52.100
EVERYONE I HAVE FOUND A WORKAROUND! (PC only I'm afraid)
With MC Command Center you are able to remove buffs/traits. Here's what you need to do: download and install MCCC > testingcheats on > right click your sim > head over to MC Command Center > MC Cheats > Cheat Sim info > Mood/Buff Control > Remove Buff and then remove the vampire weaknesses you don't want one by one.
EDIT: Apparently everytime you restart the game it resets which means you have to do it again everytime you start the game
Unfortunately this is what I have had to do as well. Removing the buffs every time I play with MCCC has been the only way I've been able to play after drinking the reconfiguration potion. I even tried humanizing and re-turning my vamps to see if it might reset, but no such luck.
Some weakness buffs get stuck as well unfortunately, particularly Withered Stomach, Uncontrollable Hissing, and Eternal Sadness. I also find it unfortunate that the withered stomach trait does not allow your vamp to consume plasma fruit salad without getting sick, but not sure if that's a bug or unfortunate gameplay consistency oversight.
