Except for Rockingham? Which works and it's even recommended in the first message of this thread to run 0.6K6.

I'm running 0.6K6 and wanted to upload a hotlap from UF1/WE4, but LFSWorld says: "Westhill hotlaps must be driven with version 0.6H or up."

I thought 0.6K is higher than 0.6H. Am I missing something?
