Light Cruiser sinks with one torp hit

[Punisher_1]

I took one torp to the bow and the whole ship flooded.

The ship had all the anti flood, reinforced bulkheads and many bulkheads along with auxiliary engines for improved flood control and the like. While the Brit light cruiser took three torps and was still afloat even though it had massive damage and the like. 

Something seems broken here.

*rolls eyes* See details, what exact components did both ships have, where did the torpedoes hit? Fresh areas or damage saturated areas? What size of torpedoes? What were crew casualties like? What previous damage was sustained? What was the displacement of both ships? If you can't list out the facts for proper investigation then this isn't useful information.

Maybe the enemy has developed bigger torps then you?

It is pretty common for some ships to take one torpedo and sink while others suffer 5 flash fire and are fine. Its generally a known issue

Were you using 18" torps and the AI using 22" or similiar?
A 22" torp will normally 1 hit a CL.

Also I've noticed the AI favouring high levels of torp-belts as well.
