Hey there. I opened a support case with the details of this problem, and as usual was thanked and told that this is a known issue. Unfortunately, they apparently don't know what the issue actually is.
Before the major patch two weeks ago, my set ofgold resistance jewelry (Flame Resist/Ward III on the earrings/rings/bracelets, flame resist crystal in the necklace) was eliminating all damage done by the Scorching ability of the flame and fire beetles. Since the patch, though, they don't have any effect at all. I also checked with the Immolate effect, and they don't make a difference there, either.
Has anyone else had any similar problem with resistances since the patch? Can anyone say they're definintely *not* having this issue? Just trying to figure out what exactly the issue is... flame resist, all resists, resist jewelry, or whatever.
