Adding listen checks back to invisibility?

[Ronan]

I'm not all that familiar with NWN2, but from what I understand OE made some changes to invisibility in 1.23. EffectInvisibility now silences the affected creatures so they can no longer be heard by listen checks, correct?

Has anyone looked at adding this back in, so that it is possible to hear invisible creatures again?

I'm willing to do the work, but I've never looked at writing a plugin before and don't know how feasible this is.

Thanks.
