# Method to make character roam map isn't working

I'm an absolute beginner in Unreal Engine, so sorry for any strange mistakes, formatting, etc. I'm trying to make a game for a project where an enemy chases the player through a maze when it spots the player, but when there's no player it roams around the maze. I have the following blueprint:

Every time I run it, it has varying outcomes. Sometimes the enemy will move around a few times, then randomly stop. It won't return a fail message or move. Other times, it will send a single fail message as soon as the program is run, then not return anything else. And other times, it won't send anything at all or move and just stand there. It'll also sometimes simply turn ~95 degrees to the left then stop.

There's also the issue that the enemy takes the same path every trial, even though it's supposed to choose a random point and move to it.

The enemy easily chases the player through the maze and won't get stuck anywhere, but for some reason the enemy stops moving when it's executing the roam method.

I tried adjusting the radius in the GetRandomPointInNavigableRadius part, but that didn't affect anything. I also tried making the character smaller in case it was getting stuck on certain turns, but that also didn't affect it. Removing the delay made it work a few times, but then it went back to not working after a few trials.

Here's the rest of the code for reference:

and a picture of the maze:

and the enemy's width relative to the maze path:

Thank you for any help!
