Why target don't falling and moving in the 4.12.0 version?

Trouble in the video: - YouTube

Spawned or placed in world targets don’t falling and moving to me when I cast to GameMode.
Why?

Hi fear-sAs,

I attempted to reproduce this in 4.12.3 in a new project, but I wasn’t able to get your results. Are you able to reproduce this behavior in a new project? If so, can you provide detailed repro steps?

If it doesn’t repro in a new project, can you provide a small striped down version of your project with the issue?

We haven’t heard back from you in a few days, so we are marking this post as resolved for tracking purposes. If you’re still experiencing this issue, please feel free to post back here with additional information to reopen the post.

Cheers,

TJ
