DO NOT ESL-FLAG THIS MOD, IT WILL NOT WORK PROPERLY IF YOU DO!!!!
Many of the mods allowing you to revert the werewolf transformation at will do so by forcing the counter to almost zero. This works, but it becomes a problem if a duration remover mod is present, as the counter will be reset before the reversion can occur. Others may place the revert command within preexisting werewolf functionality, but this runs the risk of accidentally reverting if you hit one of these commands by habit.
This mod circumvents all of these problems by a) routing the revert command to the sneak key (default left control) which is not used by the werewolf for anything in the vanilla game, and b) simply setting the transformation handler quest to the shutdown stage, effectively forcing the reversion.
And to top it all off, this mod does not modify any vanilla forms, so it should be compatible with anything.
