"Should be implemented in child class" error

Hi everyone, I recently started using Unity 5 b18 and this error gets spammed in the editor (only in the the editor and not playmode).

“Should be implemented in child class”. That’s honestly all it says.

It lags the editor really badly and whenever I try to build, it stops itself because of the error.

Anyone know what’s going on?

Thanks

Alright everyone, I’ve updated to B19 and the issue seems to have gone away.

I’ll leave this post up in case anyone else has the same problem :slight_smile:
