Dual Casting Fix Mod

SKSE plugin that fixes a vanilla bug which causes the game to treat dual cast spells as if they were single cast.

Description

Casting another spell (via Cast/RemoteCast/AddSpell script functions or perk abilities) while dual casting, will break dual casting effects and perks (eg. Impact) that depend on it. This can be replicated on a vanilla load order + Survival Mode or if you have mods such as Strange Runes which calls AddSpell() while casting hand spells.

This plugin fixes that by preventing scripted/instant spells (which cannot be dual casted anyway) from disabling dual-casts.
