Alright, so I thought I remembered how to properly change levels...should have brushed up. The last time I attempted was sometime in 2002...The map transition works, but none of the weapons carry over and my character is facing the wrong way and cannot move. I made the stupid mistake of not adding info_landmarks before compiling and running through hammer! Whoops...
I have my mod set up to run through steam...it shows up in my game's list. I make a change and compile, and then run it through steam to test.
This is what shows up in my console:
"Loading game from SAVE\hrc2a1.HL1...
ERROR: couldn't open.
Loading game from SAVE\hrc1a2.HL1...
Loading decals from hrc1a2"
Here's what the change area of both maps look like:

I know it's a bit messy...I've learned my lesson. Going to be paying attention to the grid from now on.
