Of course I did. I used nandsimulator on a virtual machine to test all 
patches. Perhaps my error was testing them all together (with 
read-disturb) and this got lost somehow. It's very strange you got 
compilation errors. I'm sorry for the inconvenience. Will look into this 
today and upload a new version ASAP. (with all previous comments 
addressed as well)
