Hey, when I open monster it takes about 5-10 minutes to load and when I go into a world it closes itself no error just closes after about 2 minutes. I looked up how to make it lag less and it said to use this in the advanced options, -Xms2048m -XXermSize=256m -XX:NewRatio=3 -XX:SurvivorRatio=3 -XX:TargetSurvivorRatio=80 -XX:MaxTenuringThreshold=8 -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:MaxGCPauseMillis=10 -XX:GCPauseIntervalMillis=50 -XX:MaxGCMinorPauseMillis=7 -XX:+ExplicitGCInvokesConcurrent -XX:+UseCMSInitiatingOccupancyOnly -XX:CMSInitiatingOccupancyFraction=60 -XX:+BindGCTaskThreadsToCPUs -Xnoclassgc. It worked on horizon but it didn't help with monster? Some mods weirdly uninstalled themselves but here is the pastebin thread.http://pastebin.com/a1pkF99X. Also how do I get rid of the mapwriters mod it doesn't show in the mod folder?
