From a1459a9eac4eeb35a6c578a8b8f96393f87ed53d Mon Sep 17 00:00:00 2001 From: SmallJoker Date: Sun, 26 May 2019 09:54:23 +0200 Subject: [PATCH] Fix persistent ^[brighten after damage again (#5739) The old texture modifier is restored by passing `m_previous_texture_modifier`. Either copy it manually or let the function parameter do that.
