Initial reaction to someone destroying your hard work and vandalizing it with tribal symbols and such. (I know that one used to be for peace. Ya.)
it doesn't matter what it
used to be, it was still an emblem of the national socialists and so it's very disrespectful
but that wouldn't be my reaction
I'd have some sort of autosaver that doesn't overwrite the latest one each time set up
because griefing isn't the only thing that can go wrong
