Some errors don't show in the web console

[Jadiction]

I'm unsure of why so far, but NPE errors seem to not show in the web console sometimes. For example, when this error showed, only "null" was shown. Additionally, some random things don't show like plugin tags. Such as: "[PluginHere] Successfully loaded!" will show as "Successfully loaded!"

Essentially I'd like it to show everything a normal console does.
