Have been craftingsince server got up and this is very common.

With something that's supposedly 90% & 80% success rate, there shouldn't even be a 4 in a row occurrence if you take the rule of probability into account.

Most I had was on my weaver failed basic synthesis (90%) 5 times in a row.

I don't really have a problem with this but I would account it as an error or just pure bad luck (that happened over and over again from obt onwards)

Please clarify. Thank you.
