From 45e48295d203b653041404a75c6e2744b78ced45 Mon Sep 17 00:00:00 2001 From: Paramat Date: Wed, 16 May 2018 20:49:46 +0100 Subject: [PATCH] Pointed_thing_to_face_pos: Avoid crash when player is inside a node (#7342) Avoid crash in some situations when player is inside a node, causing 'above' to equal 'under'.
