For those having problems with proverek map .
delete the folder as highligted in the picture , thats the proverek map .
After that go into steam and clear downloadcache as in the picture .
then join skunck and let me or Las vote proverek , it should download automatic ..
It can take some time before it starts , steam workshop has to download it .
then all should be ok .
At leats this worked for me .
