Well, it was bugging me, so I took another whack at the pinata... I just tried loading my patches onto my backup FI, with a clean install of 3.0 and all factory patches confirmed working.
I avoided the WRITE all button this time and loaded my patches individually, and they worked again with the light clipping, but this time all the factory patches were replaced just with a dry bass signal. I reloaded ALL the factory patches using the WRITE ALL button, reset my FI and confirmed everything was back to original 3.0 and working. Then I loaded just one of my personal patches, reset my FI and everything was still working. So, just for kicks, I loaded my personal patches again, but went slower this time. (like, load a patch, stop wait a few seconds, load another patch, etc). I wouldn't think it would make a difference, because the write all function went quite quickly. Maybe I was just going too fast when loading individually? Now both personal and factory 3.0 patches are working on my backup FI.
Moving back to my main FI, I followed the same process... reloaded all 3.0 patches via the WRITE ALL, reset, confirmed, etc etc. Selected a different directory to load my last three patches, and... editor crashed. This was a little different, because when I loaded the last three on my 2nd FI, I navigated to the other folder AFTER hitting the WRITE ALL button. This time, I loaded the first twelve, then tried selecting the different directory through Editor's file menu. Had to restart my PC to load the last three, but achieved success!
All personal patches loaded and all remaining factory patches working on both Impacts.
To satisfy curiosity about the light clipping, I loaded 2.22 back on my 2nd FI to see if that solved the issue. Reset, and... no sound. A quick WRITE ALL of all 1.00 sounds via the 2.22 Editor, reset, and all factory 1.0 sounds working. Loaded my personal patches individually, and everything is working on 2.22 as well.
I'll have to do some more troubleshooting to find that pesky clipping issue is because it's still there even in 2.22, but all patches loaded and working on both Impacts in 3.0. Very strange about the factory patches disappearing after loading personal ones.
