If the other player is using a kb sword in water you legit cant move. You get stuck in a block and cant move and your just glitched and thats one of the main issues but there are a couple more. Bow boost is glitched so sometimes (i mean a lot) you just get glitched back while bow boosting. There is another big glitch where pearls dont land, This happens a lot where you throw a pearl and something with no stuff where you threw the pearl makes it not work and basically the pearl was useless. These are just countless bugs that are making kitpvp unplayable dying to the stupidest reasons.
It might just be your internet...? I never have any of these problems. Every now and then I might have pearl glitches and I rarely get lag stuck in blocks.
Kb sword gets a player stuck in blocks, people have already brought this up in past suggestions so make sure to make a suggestion or complaint that hasn't already been made.
Trust me its an issue using a kb in water gets people stuck in a block I think it has something to do with the anticheat but im not sure it might be something else.
A LOT of people quitted kitpvp due to these annoying glitches. You Tage so gard when your stuck in the water becuase someone has a KB Sword. Remove all kb2 and replace with kb1
