So I started my server about a week ago for me and my friends to mess around on and it ran alright until recently I've come to the realization that lots of things weren't working right. The main problems are that water doesn't disappear after the source block is gone, leaves aren't decaying and explosions don't destroy things despite having MobGreifing on, among other things. I'm sure that the problem has a relation to Block Updates and them not being registered, but I have no idea how to make the server acknowledge them. Any help would be appreciated!
