Before me and a few friends wanted to add 3 mods which were ExtraTIC, ProjectE and Iguana Tweaks. Unfortunately this caused the world to corrupt but not instantly and just after time. Every time a player joined the server would crash and give me the error The state engine was in incorrect state SERVER_STOPPING and forced into state SERVER_STOPPED. Errors may have been discarded I tried loading up the world in Singleplayer and my game instantly CTD which lead me to believe the world was corrupt. I'm saying this as i wanted to ask if there was a reason why i shouldn't add these mods and if i can, which ones?
