I am experiencing this since few days.
I often use setup which goes like this: throw -> unblockable spine splitter -> light skull splitter during stagger -> auto double
Recently I noticed tusk does not do Auto Double, but Immortal Spirit linker for some reason. I am not inputting qcf+kick, I dont understand why this is happening. I am used to do kick auto double after light skull splitter and this sudden change messes with my brain, I totally mash rest of combo because it confuses me.
What is weird, punch auto doubles work fine, no Skull Splitter linker after light skull splitter.
Anyone experienced this? Maybe eyedol patch did this?
