What does "Gone Ohmic" mean ??

as in, it shows resistances via an Ohm meter?

more like, leaking DC, or leaking period..

Or, has had its internal series resistance increase to unacceptable
levels; this would lower the Q of the resonant circuit, increase
losses, and make it less effective as a narrow-bandwidth filter.
