Hi Albrecht,
I installed your mod earlier and assume it doesn't conflict with GWX2.1, OLC's Ubermod (Scene part), Water Stream etc. etc. No errors appeared when enabling via JSGME, so hopefully it's OK.
I took it for a test run on some of the single missions, and all I can say is I survived one mission only
The destroyers kept finding me, no matter what I did - at one point a Catalina providing air-support for a convoy got a full spread around me and sent me sinking!!
This has certainly made the hunting harder, and I've only tried this up to 1942.... can't imagine I will survive much longer when I start a patrol
Good work there mate!
