No problem, I love debugging/troubleshooting.

I actually just used this method to my advantage to burn down my fire faster. (based on the fire sparkling, and when I sent someone to drink they tried to dowse the fire... hmmm...)

So I sped up the fire 3 times and it went from almost 10h to just 30m. I let it burn down to 0m, then slowed it back down 3 times. (Just in case something else is affected.) That resulted in another 30m wait... but still better than 10h!
