Save looks good and I didn't see anything in the logfile that would point to a possible issue.
Some general things to look at / ask / try:
- Do you happen to have any tree farms in the area?
- What is the amount of zombies you have set to be alive at once for the BM horde? Have you tried lowering that amount to reduce entities on screen?
- Are you able to check the event viewer log and get more specifics on why it hung up / crash? Sometimes the error code given will give us a clue to see what is happening.
- How long are you playing at the point that the horde night starts? Does it change if you restart the game right before the horde night?
- Any overclocking going on?
- What is your ram specs and what is your bios set for (in regards to the ram)?
- Are you able to monitor and record the various temperatures in your computer as you are playing the game?
- Also do some memory testing (see link below from Tom's Hardware).

With no warnings in the logfile stating that the game is trying to load up something that is either missing or corrupted, it makes me think that the horde night might be stressing out your system to the point that unity crashes (I have had 7D2D crash on me occasionally, but nothing consistently or not tied to an error I introduced in my mod)
Alrighty so I do have a tree farm of sorts near my house which is also across the street from my base, however this hasn't caused problems in the past. But to test, I cut down most of the trees around my house and my game still froze.
I have it set to 64 max alive but that hasn't caused issues in the past either. I have not tried lowering the number but I can.
I literally saved like half an in game hour before the horde so I load in and I fight the horde pretty much right off the bat. I did not try restarting the game right before the horde starts.
I haven't touched the overclocking settings in CAM and I think its disabled in my BIOS anyways but I have just removed that panel from my CAM settings which apparently disables it.
I have 16gb of ram. I'm not sure what it is set to in the BIOS. I did play around with the paging file size a couple of weeks ago because of some really bad stuttering in my Alpha 20 game but I have since turned it back to default as of like 4 days ago or something.
I am able to see what temperature my computer is at while I play and the highest it has went on an alpha 18 horde night is like 60 to 70 degrees C, however it only gets to about 40 or 50 before the game freezes.
Here's the event viewer log details :

Alright so I ran the windows memory test and it did not detect any issues
I tried the horde again with 32 max alive instead of 64 and my game still froze at about the same time (this isn't related to the problem but I have been playing 64 max hordes that I was just breezing through this one until it froze)
Something else I forgot to mention is that I can make it through the whole horde night by just leaving my player idle and doing nothing. It worked once, and it almost worked a second time except once I reached morning the zombies were frozen. I tried using that symbol on the number pad to freeze / unfreeze their Ai and that didn't work. I shot at them, still didn't work so I tried quitting the game and then it froze again.
