i tried printing in a build on a multiplayer server but the blocks dont place at all i mean they do but they just get put back into my inv and dont place

for me it does nothing i can toggle it on or off and press v whatever i want but does not place anything. it might be because there is water where another block needs to be. also on multiplayer

Should be fixed in 3.0. Check your placement range if the issue persists, I would recommend setting it to 5.
