Here is v1.21, which would be the same as v1.2:
What you have in your attachment pic looks to be maybe:
I am not certain when we added DanielCoffey's Merchant sil files in, but I thought it was around the time of v1.1... but anyway, prior to adding-in his excellent work, the sils were a bit of a mess. Some of the ships had "stunt doubles" and were barely close-looking, with some of them only ugly cousins. Also, if you didn't clean the base SH4 game folder and the Save folder, you can end up with a mix of mods and Stock, which would show in your RecMan.
-----------------------------------------------------
Now, we are going to delay the v1.21 release a couple-three days, because we did manage to discover the issue as to why some of you are experiencing deaf IJN escorts, and that's because some of them are. It all depends upon which ship you encounter, as to which sensors they use. Some of the sonar and hydrophones do not work properly. We'll need some time to adjust things in that regard. We definitely do not want to go too strong, and we do want to include the choice for the player to go stronger if desired. So give us a couple of days, and we'll shoot for Friday or Saturday for the release.
