In my multiplayer server there seems to be an issue with placing blocks that are a little too far.
When I place a block on a spot that is usually reachable, it would appear for a split second and disappear, then returns to my inventory. The only way I can place the block is by getting closer. I have no clue what is causing the problem.
Breaking blocks seems to be fine even when I am at the farthest mining distance.
