Here's a scene with a problem: https://yadi.sk/d/OYiRCjV23SAC8v

Now, if I change input in inputselector, trail that was already produced, will reset. Here's a video with a problem: https://yadi.sk/i/9wX1aps43SABtu

I also encounter this when I switch bypass on any scene after the trails.

Not really a bug . The problem is that some people might actually say it's a bug the other way (that the Trails *don't* reset). So I had to choose one or the other. Currently, the Trails do reset under certain circumstances.
