For the last three or so days, whenever I'm placing blocks in mass quantities whether it be on main or mining, or even on skyblock. i'll start placing a lot of blocks and getting into a rhythm and all of a sudden i get kicked for "impossible actions" every time. on June 9th it was the worst at must've happened to me ATLEAST 45 times within 4 hours. there doesn't seem to be any specific triggers that cause it. Just placing blocks. I do have a video of it happening if needed.
It also happened to me a few times, that was around 1.5 week ago when I was placing a lot of blocks for my town
