I noticed that when I return from a nested time-line, all audio effects dissapeard from the BUSSES and MASTER. The audio pluggins in the audio tracks are still there. Should I report this as a bug by the Vegas Team?
That I don't know, but I never used that Nested time line and shall never use it. And therefore I don't know when it was introduced in Vegas, but I did read the bugfixes of build VP b 321 and there stood that the problem of that nested timeline, as @joost-berk his problem still is, was fixed.
