I'm glad it was helpful. It's unfortunate if you are forced to use the old version of Arduino AVR Boards though. That version worked fine of course but there have been some minor improvements since then due to the new tool versions (most especially LTO).
Maybe if you would take a minute to give some information on the problem you had it could help to find a solution so that you don't need to always be stuck using an old Arduino AVR Boards version.
