I'm running v1.5 with U-Boat missions and it's a disk copy.
The version of OTC I've downloaded is this one -

I have tried it in a clean install, with just the OTC mod, and I still get the same issue(s). I don't load saves when I've changed mods, unless I'm in port between missions - been told that's safe.
My other mods are as follows, but the same problem is still present if OTC is the only mod.
