I imported some charts from another strategy to a new strategy. When I did this, of course, the I/O from the old strategy was also imported and PAC Control automatically created new I/O units in the new strategy for this old I/O to be housed under. I figured out I could just do Find/Replace and get all my I/O references set to the new Brain (Milton_brain) and then delete the old I/O (Newfound_Brain and Newfound_Brain_IMP1). I also did a Find/Replace on the old brains themselves because I am using Scratchpad functions which reference I/O unit. However, PAC Control will not let me delete the old I/O units even though there are no longer any references to the brains or the I/O under them. The weirdest thing is that I was able to delete some of these “imported” brains. Just not these last two. Is this just a bug and/or my new strategy is corrupted?
