Apologies if there's already a thread for this somewhere - I couldn't find anything. No major bugs so far, but there are a few issues, some of which at least are easily fixed. This is all from the perspective of a CORE novice playing USA. 
1. Malin Craig retirement event - the US got a couple of Stalinists as Chairman of the Joint Chiefs and Army Chief of Staff (Hans Amlie and Oliver Law, respectively). Putting Marshall in both offices as part of Craig's retirement event would be the surest fix. Note, the only ahistorical thing I've done was enforcing the Neutrality Act against China and Japan - elections have been historical, DP sliders are reasonably historical (I've pushed Free Market twice and Interventionist once). No idea why the game chose Stalinists to auto-fill the offices.
Also, looks like there's some time variability in the event since Wikipedia says Craig retired in Sept. '39, I got the event in March.
2. Spelling error - CL-49 was the USS St. Louis, not USS Saint Louis.
Other issues I've mentioned to Hagar in another thread, copied here for completeness:
3. Admiral Stark had the Logistics Wizard trait.
4. Some warship types (BB, BC, maybe others) had min positioning > max positioning.
5. (Possibly WAD, not sure) The '37 heavy bomber tech does not activate the '35 heavy bomber model and obsolete it immediately the way most other air unit techs do. So if one skips the '35 heavy bomber tech the starting '30 heavy bombers have no upgrade path.
6. CORE is extremely unfriendly to alt-tabbing. Sometimes doing so results in striped and unreadable tooltips, more often one simply can't get the game back on the screen once finished with whatever you're doing on the desktop (checking event or tech files to figure out what's going on, checking forums, email, whatever
). Unmodded AoD does not have this problem, and I haven't seen it with any other Paradox games either.
7. The manual is not completely up to date regarding some parts of the tech tree, and particularly in the appendix listing what naval builds are given by event vs. constructed in-game.
