Hi!:)
My Battle Spitter was evolved in previous patch. He got: 4 normal skills, 2 mood skills and last ('special') skill, Weak Toxin. Seven skills in total.
In new patch he got only 6 skills: as first skill is his special skill Weak Toxin, then only 3 of his normal skills and 2 mood skills as last. So 6 skills in total - and last one skill skipped to first place.
What can I do with it to fix it? I tried to teach him his lost one, normal skill but he doesn't have slot for it.
I don't know, maybe it's connected to fact that Weak Toxin is only one skill still unable to be learned in that new patch at Mrs. Zoologists from all special skills for veno pets? Other special skills (like Bone Sickle, Gold Armor Deity) are now avaliable there.
