Particle component is not visible if was not visible from start (hidden under landscape)

Hi. I reproduced this issue on clean project… However, i found “reset” which works on this clean project, but not in main project…
BTW some FXs are working, some not, for example one huge FX worked on that tower in my main project, but smaller ones not, sometimes if its too much under the landscape then its not working…

Here is reproduced issue project zip (90MB)
