Restrictions on friendly challenge only in times of war (battle day)

Thanks for the update. Our clan is loving the friendly challenge update! While I understand why the restrictions are in place, it is kind of a pain to not be able to make minor modifications to my base and have a clanmate immediately test it. There have been a lot of suggestions with regards to allowing a percentage of changes to a base, but that seems like a complete shift in the logic that has already been built. One, perhaps simpler, remedy would be to just make this a restriction during times of clan war, particularly battle day now that we are unable to see preview of the opposing Clan's bases during prep day. Just a thought...
