Hey vle07,
The bug that was entered by Eric K., UE-5049 was returned as By Design by the engineers. Taken directly from the engineer, “This is expected behavior, beam emitters have always worked this way.” This is just simply how they work, and we do not intend on modifying the current implementation as of now. This is all the information I have in regards to the issue, but if you have further questions or need additional assistance, please let me know.
Cheers,
