Spawning player at: [Load] (0.00, 0.00, 0.00) has some Transform nil BUG

I created a MOD with some mechanics, and encountered at least 2 bugs when testing player spawn coordinates at (0, 0, 0).

Hooked into playerspawner.SpawnAtLocation to force player spawning at coordinate [Load] (0.00, 0.00, 0.00).

log :   Spawning player at: [Load] (0.00, 0.00, 0.00)

Crash 1: After successfully entering the game at this location, connecting a game controller triggers a crash:

[00:01:33]: [string "scripts/components/playercontroller.lua"]:3130: attempt to index field 'Transform' (a nil value)
LUA ERROR stack traceback:
scripts/components/playercontroller.lua:3130 in (upvalue) UpdateControllerInteractionTarget (Lua) <3036-3228>

Crash 2: Still in this area, causes errors in birdspawner.SpawnBird:

          [string "scripts/components/birdspawner.lua"]:292: attempt to index field 'Transform' (a nil value)

         or 

          [string "scripts/components/birdspawner.lua"]:302: attempt to index field 'Transform' (a nil value)

Note: All above issues occurred in a save file without caves.
