dot format cannot represent the whole graph

[weishengkui]

Thank you for your great work. But I have a question.
To reconstruct the whole graph , I try to use dot output .dt file , but it seems that this format loss the final value.
For example:
ban => b/1 + a/109 + n/306 which is not true , when compared to the dumped format.
Because dumped format has a final state value, like:

State: 785381 (0xbfbe5) final (2887)

So, why .dt format loss the last value(2887)?
