Hello,
I have the weird bug in BGT on newest version of SR - I cannot use summon familiar spell.
I can pick it up at character creation (wasn't it supposed to be innate?) and cannot cast it after memorizing.
It simply does not appear in casting menu (but does appear memorized in spell book).
I stupidly removed the installation (no weidu log) before deciding to ask a question, but I had installed revised SCS, tweaks, IR and some content mods.
Thanks for help.
