Bug/Issue Long loading times

Hello,

I run a fairly hefty rig for a simple pixel game, but I've noticed that load times take awhile, especially when using the /reload command for when I work on my mod. This hinders my development pace and I'm wondering the reason for such a load time of about 5-10 minutes. My mod is small and it usually only takes about 20 seconds on my computer to reload the game. Could this be an issue on my side with a poor hard disk drive, or is there something I am missing?

 

As of right now, my loading times are once again about 10-20 seconds.
