This is an extension of the bug that Volley Gun Steam Tanks don't generate Schematics since the issue is much bigger.

So far i found out that Schematics are not generated from:

  • damage dealt by Master Engineers
  • damage dealt by Engineers
  • damage dealt by any type of Elector Count State Troops units
  • damage dealt by any Gunnery unit in the reinforcing army (even if it is your own faction)
  • damage dealt by Volley Gun Steam Tank units
