SWTOR: ERROR C12
So I'm getting this, constantly when trying to exit my ship.
This program encountered an internal error and will exit.
Error code: C12
Failed to load room dat file
[/world/areas/4611686025952170568/h3g_to_h4g_trans_01.dat]
Reason: not found
You may have to reload the area to use this room by GUID [e.g. as default skyscene].
I did some research and it gave to options to fix it which were these.
Non-Streaming launcher - Log into the launcher but don't click Play. Check for small letters "ST" in the bottom left corner. If this is NOT present, click the cog icon and then run the repair option.
Streaming launcher - If the letters "ST" is present, close the launcher, right mouse click on the game shortcut, select open file location and delete the BitRaider folder. Then start the launcher
I was on the Streaming launcher first, did it what it said without success. So I switched to the non-streaming launcher and after 7 hours of redownloading and installing all of the files, then repairing the installation. This did not work either.
There is no other solution that I've found. This only started after the 4.01A patch. The original Early Access patch was fine, the bug fixes game and boom.
Try the repair utility located here just be careful it doesn't switch you back to streaming , if it looks like it does , close the launcher and re-edit the client_settings file , just mentioning just in case.
check the launcher.settings file after running the repair utility before launching may be best.
