Bugs in 3.0.3

I have a variable @DroughtOnSac@ with the value Y:\ and another variable @DroughtOnDrive@ with the value @drive@\Documents\\co2 drought

Using sync with mirror or copy (and probably the others too but I haven't checked) I keep getting the error "Failed to copy Y:\\test.txt" for every file that should be sent to the other drive. It looks like it's trying to use "Y:\\" instead of "Y:\". I'm sure this used to work.

Also in playing with this, I've found that a bug in the sync tab.
Select insert variable, in the drop down box choose "DroughtOnSac" and click the plus sign twice and you'll get an error like "The exception unknown software exception (0xc0000417) occured in the application at location 0x7858c955".

My variables.ini follows with some personal stuff changed.
I think the first line probably shouldn't be there, but it is.
