*MAJOR* bugs

I am constantly catching on fire from dying, but when I die I cannot see my ghost, just the underneath shadow. I cannot click to haunt the portal, I have to use my space bar(which I figured out after a long time of floating around as a ghostless shadow). I cannot attack anything, I simply walk up to it. Using the mouse OR force attack button simply causes me to awkwardly walk up to any animal but not do any damage or attacking.

This is really making the game unplayable as I cannot attack anything, and the other bugs are VERY annoying to have to deal with 24/7.

EDIT: I have tried uninstalling and reinstalling, and verifying my files.
