AACW has reached the end of it's development. Barring a very glaring bug there will be neither updates nor patches for it unless the Devs suddenly run into a large amount of time on their hand; which is far from likely.
But to your bombardment casualties, you should be getting a bombardment report during the turn resolution which only consists of the game focusing on the regions in which the fleet a bombarding artillery are located, with the bombardment sound track played and the bombardment icon appearing momentarily.
After the turn resolution you will have a report in the Mail Box stating either that Fleet-What-Ever bombarded your units in a named location achieving x hits and receiving y hits in return or the other way around, depending on whether it was your fleet bombarding or your land unit. This report is the indicator for you to look at you bombarding units in the reported location to check their status.
There has never been a report of ships nor units lost through bombardment and at this late date there won't be either.
