I got some small issues when I update to 4.18 from 4.18 preview 3

alt textI just updated the newest from 4.18 preview 4. And I got some small issues. Some of my modular synths did’t work in the newest version. And when I build lighting quality, there is some issues, either. They all didn’t happen in old preview version. Is there any way I can back to 4.18 preview 3? Because I have a workshop in next week. I don’t how to fix that. But others are all great. Thank you.

I’m not sure about the lighting but you might need to re-add the synthesis plugin in the new version, although if some of them are working this obviously won’t fix it. I had to do this when moving to 4.18.
