I run two version of ngind : 0.1.3 and 0.1.4
Apparently they are building two different chains which one of them (0.1.4) is about 9500 blocks longer than the other one.

So when the dev team are/is pretending everything is right, you guys should

1- If you want to mine, use the last version
2- When ever a new version is released, take care about chain branching (It happened once, it can happen in future)

P.S. about 4-5 days ago the difficulty drop from 220kh to about 90 Kh, I think at that time, dev team decided to change their wallet from 0.1.3 to 0.1.4 and a new branch is created. Obviously this is a bug, a new release should not lead to a new branch. The point is when a new branch is created, there was 80~100 kh mining power that was working on nothing! and it continued to mine nothing for days because the dev team ...  (I don't want to continue my sentence)
I am a newbie and probably I am wrong. You pro guys (@Avahad @searchain @...) please correct me
