I thought maybe that is what could have happened, but then again my base was fine. And I don’t think it was a case of it decaying and no one being in the area, since two of them are at obelisks one being sinkhole, they should have gone poof if it was decay. Oh well, I guess I will never know for sure, but don’t think I will get them back. Thank you for the info, I will be careful about the switch from summer timers in the future in case that had anything to do with it
