Max amount of mobs that can stack is now 9999 compared to an infinite amount as it was before. Updated MergedMobs plugin to address a bug that can cause a serious server crash. Several miscellaneous changes, we apologize for the downtime throughout the day, stability should be much better now. (thanks lee ) We are going to try out the new update and max amount of stacked mobs before applying to .net. Edit: Stacked mob limit was reverted back to how it was.
