Yesterday, before my SH decided to take a bungee jump without the rope, i found out rather strange bug.. or could i even call it a glitch.
It's related to the specialised crew members (engineers, radar etc), On my 5th patrol in my Graf spee, i noticed there was a engine specialist for me to be recruited, of course i take him aboard instantly (sascha.H.something) was the name i guess, i send out to the sea right away after i notice that i forgot to promote my crew members.
I reload the autosave, and guess what. Sascha is at the recuirtable crew list AND aboard my ship. And i still have same amount of renown BEFORE i recruited him.. I ended up confirming this 3 times by restarting the game and doing the same. Now i got a graf spee crew with 10 clone engine specialists
