ArgumentNullException for spriteBatch.Draw in monogame

[lurv]

So my game has code that checks for enemy spawns every 0.1 seconds.

I store my Enemy objects in a List<> and draw all enemy objects at their positions in a foreach statement in the Draw() method

Basically, my problem is that every time I add an Enemy to my List<> anywhere but Update or LoadContent it throws ArgumentNullException because some value is null?

It doesn't say which value is null, but it highlights my spriteBatch.Draw

EDIT: Just checked and apparently the texture2d value is null, why is this?
EDIT: Fixed

I would assume because it's either not set anymore or never set before you get there.
