With the new update, the release stage gets cut off very abruptly after a few seconds when it is set to "very long" (haven't checked the exact value). If you take for example B-15 "Planet" (restored from factory defaults after the upgrade), the sound suddenly stops, while it should have gone on for quite a bit longer, and should fade out gradually.
I can't recall hearing this behaviour in patch 2.7, which I'm sure I would have as it struck me immediately with 2.8.
Can you please look into this?
