From 0b4dec63a912bbc054f18689c73bb0ab9cc0c260 Mon Sep 17 00:00:00 2001 From: Hein-Pieter van Braam-Stewart <hp@tmm.cx> Date: Fri, 19 Apr 2019 22:03:00 +0200 Subject: [PATCH] Object::script may not be a valid Ref<Script> It appears that Object::script may be a valid ScriptInstance but not be castable to Ref<Script>. There were only 5 places in the code that made this assumption. This commit fixes that.
