Forgot to add the stone fireplace glitch is happening on the second floor of a watchtower. Unknown if this makes a difference

on the topic of stone fireplace currently are unable to put cooking pots on the stone oven while inside even if the roof is well above the height limit of the fire

Figured out how to make the glitch work every time. Steps to reproduce ignite fire in oven, let it burn out, use the re ignite option after adding another log, then once that burns out add a log.
