I don't really think this is a bug, just something I did... but in case this happed to someone else its in this area...
Working on project mix and all was well for a few hours, then the project stated to drop out..
The audio meters where still moving but no would.
What did I do? I did notice that 3 ProCh tracks popped on just before the issues...
I back tracked and removed the plugin that I just put up and removed two busses.
Still no luck.
I saved it as is and rebooted a few times and restated Splat and the project.. ever time the same problem. I tried a few things to see if I could fix it but nope...
I did make a video of it happening as I reset Sonar a few times and tested it... I will get it up later.
Good thing I save with new file names every 20 munities... I opened the version before the problem and continued on with no issues... :)
