I added a safety net for negative numbers, and a config for laser state along with the required commands. There is now a warning if the config is corrupt, but corruption doesn't really matter in my case. If the file is corrupt, restarting the server should suffice in fixing it. Some commands like listing all active particles should work now.
IF THERE ARE ANY BUGS PLEASE COMMENT AND PUT A BAD REVIEW SO I KNOW THERE IS SOMETHING TO FIX!!
I WILL FIX IT WITHIN A WEEK, BUT MOST LIKELY BY THE END OF THE DAY!
