[First of all sorry for my bad grammar.]
While playing, I use buckets to preventing fall damage with water, farming, etc. And while using that, it disappears(bucket stays empty and water/lava disappears) sometimes, after that, If I right click, it spanws lava/water again, and sometimes, it stays on the block where I put the water/lava before, but it stays invisible. Like if you right click that block, it gives you water/lava. I do not know why this keeps happening, I searched this issue on this forum, but I did not find anything. Its getting annoying when it happens much.
NOTE: It disappears randomly, not like putting water on it or etc. It just happens randomly. I do not use anything for that.
It looks like
MC-8930 but it is a bit different than that.
