My issue keeps getting closed before I can get any assistance.
Still experiencing a major lag spikes. After ten minutes the game just starts lagging, even if I just stand idle. It lags for 5 seconds every 3 seconds. I do not have anything from fish's undead in my inventory. I exit the world and reload but lag is back immediately, even if I load a different world with an empty inventory. If I close the game completely and relaunch the lag goes away, but always returns right around ten minutes in. Allocated 10 gigs of ram, Java 1.8.0.51, no additional arguments.
