The server crashed while I was playing with 1 friend and after that I cannot resume hosting the server anymore.
"Dedicated Server Failed To Start: There was some kind of trouble starting up the server. How odd."
I attached the required files that I could find, please let me know if any other files are needed. (The Steam .mdmp file was not found according to your instruction).
I was building pighouse in cave when the server crashed. I tried to restart Steam and verified integrity of the game cache but didn't help.
