Hi Joe and Brian ( or I guess All, really )
Although I haven't experienced the Solo delay bug yet myself, I was thinking that a possible work around would be to use the Scene capability in SAC for the cue wedge ( or IEM cue ).
Possible steps to do this:
1. Activate a second output on each monitor mix (output 2, 3, whatever) and assign that output to an unused pair of outputs on one of the preamps then wire that preamp output to your cue wedge.
2. Create a scene for each monitor mix that mutes the "cue mix" output on all mixes except the mix to be monitored, and Un-mutes the "cue mix" output on the mix to be monitored.
3. If you are using plugins on the Master mix output of your mixes, you would obviously have to change you Master output to be one of the outputs 9 through 16 and then route that output to both the actual monitor mix out and the 'Cue" out. so you would here adjustments
This should solve the problem right? Since you are not even touching SAC's solo bus at all.
Just trying to help with an interim solution, or maybe you're already doing this
