Well, I hope this helps... I set it to the forge profile for the aforementioned version... start_testlog.log is the log for starting a singleplayer game named testlog... I started to the game punched out some grass and a tree, then hit ESC and quit out to the title screen. Then hang_testlog.log is where I tried to load that singleplayer game without quitting from the title screen... it would splash the screen with the dirt tile and hung with a 0% frozen on the screen for a few minutes... finally I hit ESC returned to the title screen quit the game... and did a relaunch from the launcher... the final_testlog.log is where I went into singleplayer and loaded the game... I confirmed that my inventory of a few seeds and birchwood logs were gone... I was a no longer on the stump where I quit earlier, but rather at the original spawn point... I couldn't see anything out of the ordinary in these logs, but hopefully they will be more valuable to you.
I also want to note, I made sure the mods folder was empty
Thank You for your help
