First, I want to start by saying AMAZING work with Legendary Heroes! You guys are really expanding an already great game into an even greater one.
I've been floating around this forum since WOM (and played since WOM
) but never dove into the conversations. I figured it's about time, so hello gang 
I'm on my first play-through of LH, playing as the Kingdom of Gilden, and have finished researching Blacksmithing (allowing me to train the Iron Golem). This is where I think we've run into a problem. The Golem doesn't appear in my list of units to train or in the design list, but it does allow me to design one. Once I save my design of the Golem though it still doesn't appear in any list. I closed the game and checked the Units folder where custom units go and it was there. (well 2 were there because I tried designing him twice). I relaunched the game and still no Golem in the lists but I did notice that it did something strange to the research tree under Blacksmithing.

It added 2 more Iron Golem icons under Blacksmithing and also in the bottom right window. They say Iron Gaurd because that is what I named my design. I'm pretty sure that wasn't suppose to happen 
That's all I wanted to point out for now, and I hope I'm posting this in the right place. I'll keep an eye out for any other strange things!
Take care everyone!
