After i updated to 2.8 my stoked kiln started to get very RNG, anything from couple of minutes up to 10-15 mins to cook(fire?) any of the unfired clay items. The cracking animation starts and disappears through the progress, it looks like it resets.

after updating to Release 2.9 cooking time is now on average 10 ~ seconds on any items that are placed in the stoked kiln with 1 or 9 hibachi, not sure if that is intended but i am not complaining, much better than 2~15 mins
