Game works fine until you ride horse to where game needs to load new chunks - new chunks will not load - I can ride horse out of rendered terrain and "float". When I dismount, all un-rendered chunks begin to load. If you mount horse while chunks are loading - loading slows to a crawl and riding stutters.
