So, i got the Plugin and started it. Just seconds after every start, my console tells me:

"Error while compiling TankCommander: 'BasePlayer' does not contain a definition for 'MountObject' and no accessible extension method 'MountObject' accepting a first argument of type 'BasePlayer' could be found (are you missing a using directive or an assembly reference?) | Line: 523, Pos: 28"

How can i fix this issue?

Replacing line 523

 player.MountObject(mountable, 0);​

player.SetMounted(mountable);​

seems to have fixed it for me.
