Does the issue occur in the editor or during gameplay?
Gameplay
If it's a gameplay issue, please specify which movement system and camera type you're using (free movement vs. grid movement, third-person vs. first-person) or N/A if not applicable:
grid, first person
Briefly describe the issue you're experiencing:
Occasionally when a map loads, the external console will flood with errors and FPS will drop very low.
Are there any errors in the in-game debug console or external console window?
Yes.
Provide the steps necessary to reproduce the issue:
I don't know how to reproduce it. It seemingly happens on any map randomly, even when a map doesn't have a conveyer (see error).
Provide a download link to the bare bones project (if applicable):
