Created by: M5oul

I checked the blockchain with sync --cautious, at 97%, upper than block 37500, UnitBase issue:

That's why Test-net network is strange.

Ok, I said a mistake with my not updated node. It's fixed with https://github.com/duniter/duniter/commit/af92202cbe1920e449153d23f678666a6412f0d1. Finally, It seems my node sync well. Strange. I don't know from where come this problem on the network. I could have missed to check blocks before blocks 37.000 where I didn't use --nocautious option.

I've made a full sync --cautious on duniter.org:8999 this morning using v0.30.16, and the blockchain is fine.

The problem is a combination of #585 (closed) and #587 (closed).
