I know you are tired of the ships already, but here it goes anyway.
Good points to report:
1. The Minensuchboot 35 is now listed as such.
2. It does actually fire its main weapons.
Bugs still present.
1. The combined power of all guns (2x 10,5cm, 1x double 3,7cm and 2x single 2cm)of a Minensuchboot 35 with average gunners and a fire rate of 5 is not capable of reliably sinking a tanker while going along side it at 300m for 20 minutes! This is the state of the tanker after 20 minutes, still going at 20km/h!
2. Contrary, the tanker armed with the (that is the listed name) 3 inch 20 QWT MK.I can one shot the Minensuchboot. Additonally, in the chat window the cannon is listed as a 5 inch 20 QWT MK.I. Though the only 5 inch cannon mounted on armed merchants was the AMERICAN 5"/51 caliber gun.
Just to show you how obviously different these two cannons are:
http://www.navweaps.com/Weapons/WNBR_3-45_mk1.htm - British 12-pdr [3"/45 (7.62 cm)] 20cwt QF
http://www.navweaps.com/Weapons/WNUS_5-51_mk7.htm - US 5"/51 (12.7 cm) Marks 7
So, what gun is this supposed to be and why is the Minensuchboot made out of paper?
3. The platform on the forecastle of the tanker seams to disappear (destroyed without debris??) and therefor the gun mounted on it will float in the air.
4. The top speed of the Minensuchboot 35 is wrong. It can only travel at a max 20 km/h, though its top speed actually is 18,2knots = ~33km/h.
5. Important: All armed merchants, both British and US, had their big caliber cannons mounted at the stern and not the bow!
6. The US did not arm their merchants during the BoB and until 17 November 1941, so there should be no 5" gun available for the merchant tanker.
Seriously, do you devs actually test any of these new additions to the game??
