cant jump challenge

So far we have only 1 server – this is a hardcore server, that is, complicated options (increased hunger, fatigue, etc.). All glitches, bugs, dupes, AFK-auto-farms, etc. on the server are disabled, prohibited, and when new ones are discovered they are immediately corrected. We want the player to feel comfortable and not come across cheaters and other dishonest players, so we use only paid anti-cheats and software, like many plugins on the server. The server has an RPG orientation, which means many new monsters, bosses, riddles and secrets, as well as improvements for weapons/armor, such as runes. You can find out more about all this on our forum.
