Issue description

WailaExceptionHandler.java improperly handles null error providers as it tries to hash null in the ERROR.contains(null).

I was able to mitigate the hard crash by inserting the following code before the ERRORS.contains(provider) call:

		if (provider == null) {
			Jade.LOGGER.error("Caught unhandled exception : [{}] {}\n{}", "Unknown", e,
					ExceptionUtils.getStackTrace(e));
			return;
		}

The error that is triggering the issue:

This bug also prints out a nice rainbow in the sky if you don't crash

If I had to guess, this issue would be related to the BufferBuilder Rendering changes

A temporary workaround for now is to disable fluids in /jadec config -> mod menu
