What block specifically? I am unable to reproduce this with glass, leaves & piston blocks

B4rCodee commented 1 year ago

i have been using leaves and fences placed next to eachother and got spammed for simulation while walking overthem

Invalid bug report, leaves and fences work fine on my machine. Most likely the client's version got misidentified due to 2.3.26 having a bug where an exception would silently throw so grim would miss the player's handshake version.
