Describe the bug
Everytime you press f1, f5 or pull out a gun the screen goes black.

To Reproduce
Steps to reproduce the behaviour:

1. Install Flan's Mod(the latest pre-release of 5.6) and Astral Sorcery
2. Log onto a server or load a world
3. Press F1 to hide hud or F5 to go into third person

Expected behaviour
F1 hides the hud and I can still see the world.
F5 puts me in third person and I can see myself

Screenshots
It's just a black screen with the hotbar on top(if not in F1 mode)

Versions (please complete the following information):

• Forge: 14.23.5.2821
• Flan's Mod: 5.6 beta 5

Additional context
From all the versions I have used(5.6 beta 5, 5.6 beta and 5.5.2) this is the only version which has this bug.

Sounds very similar to #959

I also have encountered this issue, it renders Flans unusable as F5 mode in a plane simply blinds you. And as far as I know versions prior to this don't let you shoot the main guns on the plane.
