Solution: I removed the else statement from the integrated_forces process and left the two lines from the condition within the process and it fixed it :) Before:

func _integrate_forces(state):
	if Input.is_action_pressed("move_up"):
		state.apply_force(thrust.rotated(rotation))
	if Input.is_action_pressed("strafe_left"):
		state.apply_force(thrust.rotated(rotation + 4.712))
	if Input.is_action_pressed("strafe_right"):
		state.apply_force(thrust.rotated(rotation + 1.5708))
	if Input.is_action_pressed("move_down"):
		state.apply_force((thrust.rotated(rotation) * -1))
	else:
		state.apply_force(Vector2())
		Globals.player_rotation = rotation

After:

func _integrate_forces(state):
	if Input.is_action_pressed("move_up"):
		state.apply_force(thrust.rotated(rotation))
	if Input.is_action_pressed("strafe_left"):
		state.apply_force(thrust.rotated(rotation + 4.712))
	if Input.is_action_pressed("strafe_right"):
		state.apply_force(thrust.rotated(rotation + 1.5708))
	if Input.is_action_pressed("move_down"):
		state.apply_force((thrust.rotated(rotation) * -1))
	state.apply_force(Vector2())
	Globals.player_rotation = rotation

Hey guys, making some progress on this game but having a weird issue and I can't figure out what's happening. I'm instancing a ship scene into the level scene based on player selection. Weapon projectile instancing happens in the level scene. Fixed weapons shoot straight forward and this works fine as I'm moving and rotating until I hold the key to move backward, then all of the shots continue firing in the same direction I was facing when I started holding the key. Video example. This was all working fine prior to instancing the player into the scene. Here's the code I'm working with (please disregard the messy code lol).

level.gd:

extends Node2D
class_name LevelParent

var selected_ship = Globals.player_selected_ship
var format_ship_resource_path = "res://scenes/ships/ship_%s.tscn"
var ship_resource_path = format_ship_resource_path % selected_ship

var laser_scene: PackedScene = preload("res://scenes/weapons/laser.tscn")

func _ready():
	var ship_scene = load(ship_resource_path)
	var ship = ship_scene.instantiate()
	$Player.add_child(ship)
	ship.connect("shoot_fixed_weapon", _shoot_fixed_weapon)
	ship.connect("shoot_gimbal_weapon", _shoot_gimbal_weapon)
	
func _shoot_gimbal_weapon(pos,direction):
	var laser = laser_scene.instantiate() as Area2D
	laser.position = pos
	laser.rotation_degrees = rad_to_deg(direction.angle()) + 90
	laser.direction = direction
	$Projectiles.add_child(laser)
	
func _shoot_fixed_weapon(pos, direction):
	var laser = laser_scene.instantiate() as Area2D
	laser.position = pos
	laser.rotation_degrees = rad_to_deg(Globals.player_rotation)
	Globals.fixed_hardpoint_direction = Vector2(cos(Globals.player_rotation),sin(Globals.player_rotation))
	laser.direction = Globals.fixed_hardpoint_direction.rotated(-1.5708)
	$Projectiles.add_child(laser)
