Thanks for the upgrade Trevally! Good job!!! Much appreciated!
I usually play a few months at a time a couple of times per year. I finally made the move from 1.8, but now I see you are working on a 2.1 update to this already .. lol .. we'll have to change the mod name to OHII 1939-1941, since I never get any further than that without having to restart again because of a new update

. Too bad we can't do a true update that doesn't require a campaign restart!
I have to say that doing the missions without associated (visible) tonnage has been great! Ya, we have to fill that bar to complete the mission, but it doesn't have that same arcade feeling. It's more SH3-like for me. It just feels better to work within a time frame and sink ships of any size. Now it feels intense dealing with weather and hunting around and not finding anything for a week or two without worrying about the math. I can't count how many times I have mumbled "verdammt!" to myself

. hehehe
Everything has been working great, but here are just a few things I have encountered:
I upgraded to 2.1 along with upgrading TDW UI to 7.1.0 and finally got things working after a week or so of mod juggling. I tried to add the mtns mods (full and lite in the proper order), but had nothing but problems, so I ended up not using them.
Since upgrading OHII and TDW UI, I can't use TDW's sub exhaust anymore

. I'll probably have to post that problem in his thread (and Sub AI since that crashes as well).
I started using your Harbour Addition Environment Enhancement Mod for OHII. I read somewhere that the cranes and things like that are active, but everything I see is stationary. Looks good otherwise!
Also, somewhere in late 1939, I noticed a uboat parked in the way between the Wilhelmshaven pen and the exit, so when using the harbour pilot, my uboat headed right for it while turning towards the exit. I had to stop, backup, and guide it out on my own. This happened for two missions, but now the uboat is sitting further down, so it isn't a problem anymore from that point onwards.
Take your time with 2.1 .. no really .. take your time ..
Cheers!
Edit: Just started Happy Times .. Wilhelmshaven docks are alive with moving cranes and vehicles now. Nothing changed except starting this new mission.
