Hi madmax12ca -
Thank you for your report. I will begin investigation into this issue as soon as possible. I wanted to ask a few questions to begin our search for the solution to this problem.
What version of the engine you are using? Is it compiled from Source on GitHub or is it from the Launcher? Does this happen on a specific map only or is this occurring to all maps?
In the meantime, please be sure to also review our suggestions for how to report a bug, and feel free to edit your post if you have additional information to provide:
Thank you.
Eric Ketchum
