Crazy Craft 3 Server Crashing

Hi! Recently I tried upping the RAM on my Crazy Craft 3 server so it would run smoother when both players were on, but in doing so it seems to have messed up somewhere. When I start the server, I spawn in for 2 seconds with items in my inventory that I never had as well as the server itself crashing completely. I have no idea where the problem may be - any idea?

Should note, the server is being run on a Mac. If anyone has any tips on how I can up the RAM in the Forge.jar itself or within...
