1) OK, what I would do is
Disable the minor fixes mod & actually install this!
(not via JSGME) as it is really a fix to update 2.1, just copy the data folder to SilentHunterIII\data folder.
2) Now disable the Extra Units, U995 Rusty,Community Mods &
Bf109Reskin, now merge all these mods by copying from newest to oldest & rename mod to "U995 Rusty+Community Mods+Bf109Reskin", but first any mods with documentation (readme's) should be placed in the mods names folder so that 2 folders are there data & Documentation, the documentation folder is ignored by JSGME.
You should be able to enable this with no conflics, but leave out at the moment.
This leaves the following problem area's:
OLC GUI
Community units mod (now Combined)
Extra Units.
This is getting to be a nightmare!!
My advise is to leave the Extra Units out for now, until all the cfg files have been edited, I think you get my drift!
Just do Step 1) for now.
I could combine all mods but you would have to upload or point me to where I can download all these mods:
Extra Units
U995 Rusty
Community mods
BF109 Reskin
OLC Gui
Sorry I had to do this in a rush as I have visitors!
Cheers.
