Copying character blueprint to new project

Hello, new to blueprints. I created very simple character blueprint that makes them move forward based on this

It works but only works in the project it was created it. If I copy this character blueprint to the new project, it wont move forward. But in that new project, if I create the same blueprint from scratch, it works. I have about a hundred character blueprints and really don’t want to recreate from scratch. What would be causing this?

Well, after few more hours of troubleshooting, I guess I’ll answer my own question. The blueprint wasn’t the issue at all. When I imported some static mesh, importer generated automatic collision mesh that basically covered my entire level. And the blueprint wasn’t moving because of the collision.
Removed the collision from the static mesh and everything is working.
