TypeError: cannot read property '_actor'

Hello, I could use some help with this because I honestly have no idea how to fix it. I was working on my project and while testing some new skills I loaded the game and tired to learn them with YEP_SkillLearnSystem and it kept giving me this error: TypeError: cannot read property '_actor'. So at first I thought it was in the Skill Learn System plugin but after opening the Console to check while test playing I noticed the Class Change Core popping up. As it turns out there is some error in it. I have been trying and failing for two days to fix it. The Skill Learn System works perfectly fine when I turn the Class Change Core off but anytime I turn it on I keep getting the error. I have already tired redownloading the Class Change Core and replacing it but I still get the same error. Thanks for your help.

I've moved this thread to Plugin Support. Please be sure to post your threads in the correct forum next time. Thank you.


Plugin releases is for presenting plugins you wrote yourself.


There are only three ways how that type of error can happen, and your description suggests that it is the most common cause: you loaded an old (and incompatible) savefile.


80% of all plugin require you to start a new game when they're installed and make all previous savefiles incompatible, because the older savefiles do not contain the initialisation the plugin needs.


In case this error also happens when you start a new game instead of loading a saved file, the other two causes are:


2) incompatible plugins or wrong plugin order - please give a screenshot of your plugin manager and of the console message when the error happens, then we can check which one might be the cause.


3) wrong configuration - some plugin property or notetag is pointing to a wrong entry that does not exist in your project


you need to check the plugin configuration to solve this.

Thank you for your answer. I was not aware of the incompatible save files. It is now working properly. Thank you once again.
