Sry for my english. I will try to write correctly.
I don’t have a destroyers but probably one word in destroyer construction—>select slots is not correctly translated in polish leanguage version.
1 silnik (engine) (ok)
2 kondensator (capacitor) (ok)
3 tarcza (shield) (ok)
4 silnik (engine) (incorrect? it is a hull slot?)
5 komputer (cpu) (ok)
Please check it and repair if it’s not correct now.
