Basic summary, this particular character harasses the V40k players and has found a new trick, the ability to overload the server. What this does for us is completely freeze Vassal, rendering it unusable unless we exit out and go back in. He uses the 3.1.5 Vassal Engine. He’s started to use this exploit in the past week now, and hopefully there’s a counter or something that can be done for it.
Unfortunately, I’m not sure what it is he’s doing exactly. But the end result is that all of vassal freezes for multiple users. No menus can be accessed, no private message windows, no movement of pieces. Only a full exit/ending java itself will unfreeze it, but at the cost of losing the game itself without prior saving. What I have noticed is that before it happens there’s two of him, both in the (anonymous) name, before it freezes. One is clearly him, while the other a ghost.
