Legacy GM [Solved] Error message points to event with no code

############################################################################################ FATAL ERROR in action number 1 of Draw Event for object obj_ship: DoDiv :2: undefined value at gml_Object_obj_ship_Draw_76 (line 1) - { ############################################################################################

This is the error I am getting. However, I have not defined a draw event, thus it has no code. Running in debug mode, I'm aware of the line 1 "{" character, but how is this a division with an undefined value?! Also, when I added this to the draw event:
draw_sprite_ext(sprite_index,image_index,x,y,image_xscale,image_yscale,image_angle,image_blend,image_alpha);
it still gave the same error. Therefore, it isn't trying to draw a non-existent sprite, it's just breaking itself.

Do you delete the sprite that the instance is using? Or any other resources for that matter? What happens if you change the sprite that obj_ship is assigned to use?

Could it be that you're using "with all" or something along those lines and unknowingly causing it to draw stuff?

Never used with(all), and I found out what it was!

So, basically my game is multiplayer and a client can send a ship they've made in the workshop to the server. The server then checks it out, makes sure it is safe for space travel, and then creates a sprite from a surface and sets sprite_index to this new sprite. Now, that doesn't give the server this error. The error occured when the server synced ships, because it synced sprite_index as well (because thruster fire was part of the default ship's animation, but a different sprite than its idle). So, basically, my server said the ship had a sprite_index that wasn't pointing to a built-in resource, so clients always crashed.
