If you drag a piece of the Scrambler while it is scrambling it sets the position off.
Okay - solved that - the offScrambler() is turning off the scrambler if the wait and time added to be more than 0. Well... if the initial wait and time for the scrambler was 0 as in start scrambled, then this wait and time was being used - we needed to pass a manual wait and time into the offScrambler() function. This has been patched in ZIM 017 and the CDN is updated.
