World refuses to load correctly can see through the world and fall through it.

delete everything SPT, delete game files for EFT, something is wrong

start fresh and download the game again,

once that is done, copy EFT to a new folder for SPT

extract the patcher into the SPT folder, run it to complete,

extract SPT-AKI to the new SPT folder and run the server, then the launcher.

if you have issues then we'll go from there

all good, glad it worked
