Player and AI characters not spawning skeletal mesh when inheriting in Blueprints

I’ve been having a bit of a problem with the game I’m developing for an assessment at college when it comes to the player character and AI.

I’ve built the game to have the most basic of functionality for each character in a parent blueprint and I am then extending from that class to make the player character and the AI. When you play in the editor, the game functions just fine, but when the game is launched neither character mesh appears. The sword that is attached to the character in the parent blueprint spawns, and there is some limited input from both characters. It just seems that the skeletal meshes aren’t spawning.

Is there anything I’m missing with setting playable characters and NPC’s up with blueprints using inheritance, or is the support not there at the moment for characters to use inheritance in blueprints?,
