we used to get updates on the mudrunner MOD and nothing with the latest update of the game..Game version: v1.0 from 11/19/18 (Update 10) its been a while..I wonder if the Modder that does this Mod has stopped with the updates???
It takes longer than you think to code that stuff. He may be gone like you said, or he could be just planning something big. Who knows lol
Really hope he is still at it
