Trying to modify my object snippets however every time I do so it simply throws a warning message (shown in the picture) and then reverts any changes I make. The error appears for every single type of snippet (basically anything using your code editor).
I have managed to manually get around the problem by writing the shader code then directly modifying the .asset files, however this has only just started to recently occur (I have not changed Unity versions since this error has appeared, was working fine before). It is not project specific as it has occurred with completely empty projects (only importing the RMTK asset).
