Spellstrike with natural attacks

[Vilacard]

I was pointed to Wrath Patches as well as here as mods to possibly fix this issue, I also opened a ticket on Wrath patches.

Describe the bug
If you use spell combat alongside spellstrike with natural attacks (or at least when you have claws, it seems) you get more attacks than you should. I currently have a 2 Sword Saint 2 Vivisectionist with feral mutagen and will get a total of 5 attacks: 4 claw (one delivers the touch attack) and 1 bite attack.

To Reproduce
Steps to reproduce the behavior:

1. Have Spell Combat and Spellstrike turned on while you have claw attacks and would get a full round attack
2. Use a touch spell.

Expected behavior
That I receive only 3 attacks (1 bite and 2 claw in my case)

Additional context
If I try it with just spell combat: I get 4 attacks: the touch spell, 2 claws, and a bite. I'm not totally sure this is intended since I thought the touch spell (without spellstrike) would completely replace an attack.
