So after KerfurO got stuck on the hill between Sierra and Tango (including this in case it is related), i went to collect the hash codes myself. I started from TANGO, where i did the hash, exited the console and reentered the console again because i forgot to set compass to next server. When i reentered the console the server designation was FOXTROT (don't have pic sorry). I exited and reentered the console and it was TANGO again. (I don't know if this is an event or a bug, i haven't found anyone mention something similar).
When i delivered the report, email said report was wrong and i needed to redo Sierra. So i went to root console to check the codes that were already saved there, and i noticed that SIERRA and QUEBEC are identical which shouldn't be the case. The codes in order are TANGO, SIERRA, KILO, QUEBEC and FOXTROT.
I thought this might be related to the server designation change i described above. (I assume that when i went to Sierra the server designation had changed again without me noticing (like it did in Tango) and actually gave me the hashcode for Quebec.) Will try to replicate and reply here if it happens again.
