Console Error

Hi. Trying to set this up on my local rust server before trying it on my live server, and I keep getting these errors in console. I am using Carbon framework: 

Timer of 2s has failed in 'MBRewardOnline v1.1.0 by Barry_Allenn' [callback] (Object reference not set to an instance of an object)

Never Mind. Doing a restart of the server seems to have fixed the issue. 

Thanks for the fix.
