My Claim Flag gone (Don't know who remove it without warning or player grieved)

I was building my base in the small island to the right of Novosibirsk (Russia map) in server PVE9. I have obeyed all the rules placed my bed, claim flag, a sign etc. But today when i arrive in game, i found my Claim Flag removed; probably grieved. I am suspecting some one grieved it because a staff will generally give a warning if any rule breaking in building. The only thing that my Claim Flag was placed not inside but outside my locked door room of my base. Therefore, i am thinking somebody is procedural trying to grief the entire base by first removing the claim flag and after that slowly destroying the base (exploiting the rule that without a claim flag the staff won't pay attention to it). Please help find me out who is doing this kind of thing to me. Of course, for safety reason i purchased another claim flag and placed it.
Thanks and regards,

Hello Butter. Thanks for your reply. I will try to catch the culprit if he further do something or have a cuss on me. I don't think so though; because i don't have any enemy kind of player. I am always helping and friendly to others. It's just may be a random griever. Saw the flag aha! time to grief lol. Some stupid do things like that. Last time i was helping a guy to complete quest of the pirate and dropped the squid for him. Suddenly, a stupid come in between us and got the squid and ate it raw. luckily, i have 2 squids.

Yes Accel, that's the mistake. i don't often do it but this time somehow i did it. I keep important stuff like bed, claim flag and locker inside a vault door. This base was in progress actually. i would have later removed it to place inside (somehow forgot after making locked room). You know balancing between work and play.

Thanks Hank for the info. I thought i have to have all the 3 compulsorily. Any way, good to know.

Thanks for your info PistolPete, but i haven't placed anything in claimed area and yes first i have tested, it was clearly giving area mark white. It is an island with nothing near it. Only a player made bridge above it though. But it is unclaimed and too high. I have talked to its maker (CA_van, i think. He lives near, in Jhavesk) while in game and he agreed to make my base below. I think he made it for connecting Camp Kazan and Novosibirsk and Jhavesk. So, we are kind of good Neighbors. You can have a look at it; if any problem still persist according to rule, please inform me. Its the very small island just right to Novosibirsk.

 

Ok PistolPete i will try to look into it. If it's a random griever probably not to worry that much. Thanks a lot for the infos.
