Hi again! I checked the ambiences and indeed it seems that I definitely messed something up the last time I've made changes to them in FL Studio. I'm re-exporting everything with correct settings now, and I'll let you know when it's updated. Thanks for pointing this out!
By any chance I could reach you through email or Discord? I'd like to ask to test them out in Unreal Engine specifically when you'll get a chance and when I'm done making changes, before I push the update
