When trying a find and replace of levels[1] with levels[current] in the attached simple example, the replace on the second tab messes up:
levels[1]=levels[1]+1
becomes:
levels[currelevels[current]els[1].x+1
An immediate undo after also appears to fail to roll back all the find and replaces. Seems to only undo on a per tab basis, and only works with the “clean” replace tab. There was another thread about similar issues with paste, but not sure if this was resolved.
