Rootdredge World Map Kill

Killing Rootdredge, or any other boss, doesn't mark it as cleared on the World Map Act 3 Cruel.

The main reason is that LOOTING certain items (for example, Support Gems) is REQUIRED to mark them as cleared. In Act 3 Cruel, Rootdredge fails to drop Skill / Support Gems after killing it, resulting in the bug. Killing it again, even despite being able to loot Skill Gem / Support Gem after retries, doesn't clear it for some reason.

Here is a video of the bug. https://youtu.be/z4LGuECx2Tg
