As of a recent update, Sound objects with PlaybackRegionsEnabled & LoopRegions set do not seem to function properly. Instead of looping to the correct LoopRegion, sounds now simply loop to 0.
Expected behavior
For LoopRegions to work as expected, as they used to
Hey @Polyhex, thanks for the report – it looks like this bug was lurking all along, and happens whenever the bounds of the LoopRegion extend beyond the end of the asset.
If you need a workaround for this ASAP, you can set the loop-end to be something like TimeLength - 0.001; this should dodge the issue – but a fix is in review and should land in an upcoming version.
