Random errors

hi guys, i’ve randomly start getting errors and warnings even know i’ve not touched these files. At the moment they’re not even being used in my empty scene yet the error continues, i imagine this is becuase unity is constantly trying to compile the scripts.

usually i would just leave the errors but its stopping me compiling adding scripts. anyone know a fix? thanks

heres an image:

Someone else had a similar problem with performancetweak.js. I think that was due to creating a new scene in an old project. If you’re not using performancetweak or the underwater effects, just remove them from your project.
If you do use them then it would appear you have not added all the required packages.
