Unfortunately, I do get those as well.
There is a script at the root of 'enigma-dev' directory named "share_logs.sh" that will solve this........if you mind doing the extra work. As i understand it, you run the script in a terminal/shell window and it will strip those extra characters and create a pastebin file for you.
You can also use 'gdb' to debug your errors. Run the game in debug mode. Copy the name of resulting file....for example "/tmp/emg23453464548765342768.tmp" if you are running Linux;............. "C:/msys32/tmp/egm8652499151924152154.exe"...if you running Windows.
Open a Terminal window. (on windows open a Msys Shell Terminal, not a Powershell)
At the prompt, type gdb[ name of file you copied].
then type 'run'.
There you have it. You can use either of the two methods to debug your game. I personally have opted for the tedious method of looking through the output and figuring out where i made an error. This is only because i am meticulously saving the slightest change, so it is easier for me to know where i went wrong.
Hope this has 'helped' you out a bit. You can find on the discord channel. Or if you prefer, contact me here for anything else.
