Is it the addition of anti-VM and illegal data-size that caused this? I’m sceptical about this result. I get that unsigned and packed files that try to evade being disassembled (probably to protect their code and make it harder for people to cheat in the game) are suspicious, but can you please double-check this?

Hi -MOKSHA-,

Thank you for reporting this.
We’ll check it and get back to you soon.
