--- Comment #35 from Sam Edwards CFSworks@gmail.com 2012-02-21 04:22:08 CST --- Created attachment 39003 --> http://bugs.winehq.org/attachment.cgi?id=39003 Workaround (Lua autorun)
Drop this Lua file into garrysmod/garrysmod/lua/autorun (creating it if it doesn't exist) to work around the bug by replacing the problematic physics-prop killicon with the default.
Obviously, this will not work on ScriptEnforcer-protected servers.
