bruh I cant win :/ so any ways sorry to bug you again but basically a new issue Im having is I went to launch a custom missile I made and as soon as I did it crashed with this error: java.util.ConcurrentModificationException. worse yet it completly bricked the world so I had to delete it.
But anyways here's the full crash log: https://pastebin.com/pj3ZM8mY
Idk if this ones fixable or not what do you think?

update: well nvm I guess tried loading from a backup save just cause and I no longer had the issue so yeah. :/
