I fixed errors now I have less.    

Yes but I didn't know I could do that with all  js the files.

Ope! didn't see that file yet. So, you pretty much already knew what I said in my other post.  

And to do this I must do the same thing I did with ConvertUnitAI.js ?

A modding tip or trick: For js files like unit_actions.js, you could just have a file that amends the vanilla file so you don't have to maintain the entire original file. Just name it something like:   unit_actions_conversion.js unit_actions_convsys.js unit_actions_amend.js unit_actions_{whatever you want here}.js The file would contain only the sections of code that you change/add. I believe this only works with JS files. @Itms @Stan` anything to add to my description?
