Because the only way to add this amazing feature on machines is creating new files, me, Vdskillers, and FS Miner create this version of the mod with all machines added.
I hope you understand we can't creating a new version of the zip file every time is released a new machine. So we share with you time to time a new version of this file with new machines added.
I recommend when you put this file on your mod folder delete the old one (or the old ones) you have.
This version have all machines included on the last version plus this ones:
W190D_Shovel
WMF_CAT420F
JCB3CX
Komatsu_WA1200
CAT_D4ng
SkidSteer_hdShovel
SkidSteer_screenShovel
SkidSteer_t76Shovel
FS Miner
