Phantom is very buggy(reminds me of beta style builds), even when installed natively in Windows. When performing editing, be sure to save often. Phantom has a tendency to crash when many changes are made to a document without saving.
Also, the larger the document, the more likely Phantom is to crash.
I will continue to post any other issues and work-arounds when they arise.
