I found a fun and interesting bug. It sees that like before when you right click on your unit instead of canceling the units move orders it contrinues on it's path. Only now it moves the unit 1 space regardless of if it has enough movement are not. Thus you can explore the entire map with your Sov on turn 1. 
I've have discovered it doesn't work all of the time though and only about 95% of the time. Here are a few things that I have noticed doing that seems to prevent you from continuing to engage in unlimited movmement, but only until the next turn is processed.
- Merging Units
- Transferring Items
- Seperating Units
- Entering/Exiting Cities
- Large Stacks of units in 1 tile
When you do this for some reason it seem to not let you do the unlimited movement bug to any of your units not just the ones that were involved in the above activities. Not sure why those things effect the bug in the first place though.
