Which issue? If it's the log posted by pwcca, the building errors reported are 'normal', false error in rafmc version and aren't a cause of crash. The unexpected error at the end on the other hand, could be anything, even a random crash from playing too long. Hard to say since there was no details on where and when.
I am done with the official build but I can still try to provide fast fixes, if there are need while waiting the next rafmc's build. Please be more specific.
