Sad that the etn dev's dont say anything here, its only guessing 
They just got rid of the fact that they could make such an asshole, and have a staff of such programmers with crooked hands.
Well i wouldnt say that to fast, if it was an 1on1 copy from Monero i would say; yes ur right.Anyway this is not just an 1on1 copy from Monero. Its Monero(V7) in the basic with a lot, a lot of extra stuff working on the blockchain.
So yes, these things can happen, hell if even Microsoft can bring an update (~4 weeks ago) with bugs what crashes computers, harddisks, ''frozen'' gpu's and everything, then i wont start about all the bugs what Apple gave there users by adding updates (every year again) on the iPhones and iPads. U can only have respect for what ETN is doing.
The way how u talk is with zero respect.
