Reproduction steps:
1. Open the attached project, scene "door3"
2. Run in the editor and see the result - https://gyazo.com/e1c7afb0d576038c3f24e6b083fa0dc0
3. Now deploy the same scene to standalone and compare - https://gyazo.com/6697327e14e57646056e73da59e055e8

In the Editor the blue agents are tagged with "Blue" and red agents are tagged with "Red"
In the standalone player the blue agents are tagged with "Red" and the red agents are tagged with "Ladder" - a tag which doesn't even exist in the editor.

In the Editor agents behave as expected - red agents go to red square and blue go to blue
On standalone - blue agents go to red square and red agents don't move

Note, that it is project specific for some reason. When this particular scene gets imported into an empty project - everything works fine.

Reproducible with 5.5.0f1 and 5.5.0b1
