Plutonium

it's seem to be a missing image (the blue and brown squares are the default images when no image is loaded) so try reinstall your game or contact a plutonium staff to get further info

yep you need to have the dlcs to play them (obviously) either you buy them or
contact me on discord baloudiny69#7525 for any info

best way for me to avoid this is by playing in fullscreen boderless mode

did you install dlcs ?

is this error code come from a dlc map ?
