Holy water is not working

[mich]

Hello,

The trinket holy water (immune to curse for 30sec after drinking a potion) doesn't seem to be working.
I tried last run, I still took curse from trap and from the shade.

Starting at NG+2, the shadow curse rate starts at 125%.

What appears to have happened is that since patch 10, nothing can eliminate this extra 25%. So, on NG+1, the holy water will set your shadow curse gain to 0%, but on NG+2 and above, it will set it to 25%.

The patch notes don't really indicate whether this is intentional or not.
