I`m here to report that this stupid hacker still haunts the game. I thought he was right at first but then put some though into it.... It´s an alpha. The developers know that these kind of hacking attacks can happen and they already announced that they wanted to improve hacking security in the first place.
This guy is overdoing it imo.
Discussion has happened and awareness has been built but know this guy could stop and make those that actually like playing an unfinished game able to do so
