Removal removes bonus multiple times

[Joe Desu]

I put on and removed the golden skull twice and both times my spells were reduced by one.

I removed my ring of witchcraft twice and lost a spell 'each' time.

Previously, I only lost the spell(s) once per time.

All were ported over from EFUA.

Typical?

This is how NWN functions. Nothing we can do about it.
