Star Wars: The Skywalker Saga Mod

I know what we can add for this mod for transform it in the best MCreator mod:

• Add Grangster: A "Grangster" is a brown monster than the Stormtroopers had liberate for destroy the Galaxie! They are in Taiga and have their base who is similar to a grid (or cage). They are a little rare in the Desert (is 1% for they appear in a Desert), but they have a cousin who spawn near the Desert Bases.
• Add Maniester: The "Maniester" are the Stormtroopers who have a Blaster Gun. They shoot the player with difficulty, but, if the player collides the blaster, he's dead. The Maniester can loot their Blaster Gun rarely (rare loot). But, some Stormtroopers can loot it, but some...
• Add Terria: A "Terria" is like a Minecraft "Phantom", added in 1.13 with different texture (zombie, monster and skeleton...). The Terria is like him but this texture is "purple" and she's not like their texture with skeleton parts, but finally like this first texture (like a bird). She spawn in a cavern like the Hydra in Twilight Forest, but she sleep... in the top! We change the rules for say than she shoot Lava Ball (like Fire Ball but with a most powerful explosion), and, when the player collides him, she give to him a damage of 12 life (or 6 hearts)! When she dead, she drop in the ground 7750XP, and a Terria Claw item. We can read: "The Terria Claw can be cafted with a Wool Storm!", for give to the player after crafting a beautiful "Terria Sword"!
• Add Wool Storm: The "Wool Storm" can be found in "Secret Stormtroopers Bunker". The Bunker is a very rare structure (in the cave), and the Wood Storm is a treasure for craft some items (you can imagine the crafts with a Minecraft item of your choice).
• Add Storm Grangster: The "Storm Grangster" is like their cousin "Gransgster", but in a little more big. They spawn in Stormtroopers patrol in the Desert, and they most spawn in Storm Cage, who appear in a Desert Mountain (you create the Bunker, after you make a sand mountain for camouflage the Bunker, and the player must dig all sand mountain for discover it), for prepare their patrol.

It was the things to add to Minecraft. If a idea you do not like it, you can lose it. I hope than you love this ideas, and good work!

Greetings!

I'm running my own Minecraft Server (1.12.2) and have successfully installed this Mod. The mod seems to be working correctly in that I have access to all the items I need, but when I attempt to spawn an egg, nothing seems to happen. I've made sure that I am in normal difficulty and have even bounced around between creative and survival mode to make sure.

Likewise, I've tried to manually summon the entities using a command like "/summon Ewok" with no luck either. Is there something I'm missing? I'd really like to use this mod once I can get this to work! 

Thanks in advance for all your hard work!

I appreciate the reply!

At this time I do not have any other Mods installed. I have Forge installed with the default plugins and your own. The only other thing that may affect things would be that I have Multiverse-Core and Multiverse-Portals installed on the server itself. Could that be affecting things?
