Just because it's a pirate site doesn't mean you can leave your manners at home. F95 has a few house rules too, you know?
Secondly, even Prime, the creator of the Rogue-LE-Prime mod can totally understand Oni not wanting help with his project. Even though Prime and some on the Rogue-LE Modding Discord server have offered to help Oni several times for free.
Besides, that's not entirely true. Prime has already sent bugfixes to Oni several times, which Oni has also implemented into the game.
I just think it's a bit strong to insult someone you don't know so harshly just because he doesn't keep up with the updates fast enough for which you haven't paid a cent yourself.
