From 7317092733d1586187198662feff1d12e94784e4 Mon Sep 17 00:00:00 2001 From: "Justin Clark-Casey (justincc)" Date: Fri, 16 Jan 2015 22:44:54 +0000 Subject: [PATCH] For scripts in attachments, don't save .state files apart from the initial one as these are ignored since .state is saved in the attachment's asset. This eliminates pointless work and exceptions when an appdomain is unloaded whilst an attachment script state is persisted. Adds test for this case.
