I am having the same issue that is in this thread. And i notice something. If a use AESOP core version 1.3.1 it works just fine the plugin. If i use version 1.3.2 or 1.4 (the newsest one) the problem occurs as described by the other user.
It seens to be a problem of been compatible to the newest version of AESOP Core.
If you can check this I will be greatfull because AESOP is a great tool, and we need the features of the newest version thats why i can not use the 1.3.1 version in my Long Stories.
