Unable to Delete Wolf From Admin Menu

I encountered a bug when trying to delete wolfs. When you try the delete the wolf, the game considers them a online player. The issue is that the wolf is not a player. This issue may also apply to spiders that spawn on the alien planet. Also wolves show up as ---- instead of Wolf in the entity list.

A solution to this issue is to change the checks that run before deleting entities. A way to fix this issue is to add a check to see if the wolf/spider is a NPC. If that check returns true, it would bypass all other checks and delete the entity.

Replication Instructions

1. Create a world that has wolves and spiders enabled.

2. Enter the world and go to the earthlike planet.

3. Wait for wolves to spawn.

4. Select a wolf in the entity list and try to remove it.

5. An error should pop up saying that you can't remove a online player, which does not make sense as the wolf is not being controlled by a player and is a NPC.

6. Repeat steps two to five, but go the the alien planet and try to delete the spiders. You should get the same error message when trying to delete a spider.

Note that it is a feature for players to be spiders/wolves; players can transform into one at a medical room in creative mode.
