@isaiah I believe I found a bug. I have 2 Select boxes for Foundation with many options. I am trying to drag and drop the “Select Option” stacks from a Foundation 1 Select Box stack to a Foundation 6 Select Box stack. I can drag and drop 1 or 2 at a time with no issues. Anytime I try to move 3 or more between the stacks then RW crashes. I was able to move 4 out of the Select Box stack to a higher level container with no problem but it can’t be done between the two Select Box stacks at the moment.
I have the latest Foundation 6 theme and stacks as of today and running RW 8.7 on Big Sur. Here is a link to the error log.
FWIW, since I can drag & drop up to 2 but not more than two, this error could be some kind of memory leak.
Here is a link to the RW project file with these two stacks.
