Subject: [PATCH] Try to fix game hang caused by shelf linking.

Fixing an infinite loop caused by unchecked cache invalidation.

Sometime when you link shelves, a storageGroup in cache will not null, but with no SpawnedMember.

If unchecked, it will cause groupsOfPriorityCount to decrease by -1, which is a infinite loop.

This fix will FixCache when a group have no member.
