Version 3.3.8
When deleting a cue that stops effects (without specifying cue only) the effect will track through the entire cuelist, through all blocks, forever.
New showfile. Cue 1 thru thru 100. Cue 5 + 100 block enter. Patch ch1 as an aura. Ch1 Effect 901. Record Cue 1 only. Delete cue 2 (to track). Effect 901 tracks through Cue 5 and Cue 100 - through all blocks. This works with intensity (absolute) effects as well.
