So is this patch compatible or not? Its frustrating to not know if i can update the mod or if my save game will break.
First and foremost, keep your old zip file around when updating to the new version. Or just the old file folder. Rename it and add Old- to the beginning.
That way if the new version breaks something, you can just swap the old version back in.
Secondly, the versioning numbers tend to mark where save breaks happen. This developer seems to be marking where save breaks are happening with changes in version number. So long as you're within 11.0.0, you should be able to update without breaking anything regardless of what the RC number is.
