Bread burning in one oven but not another?

[pordle]

Last night I put in 2 sets of bread dough in 2 different ovens.
Both are on paved land.
Both are on a claim.
The only difference I can see is that one has a brick paved in front and the other has a rug in front.
Both were given 3 sticks then the bread dough put in secondary then lit.
Today I checked and one is burnt to ash and the other was not.
The odd part is that this happened previously with these same ovens. One burns the bread while the other doesn't so it wasn't a single time this occurred...
I read before about a buggy type thing where the timer will tick and you have to put in less fuel but why is this only happening in one oven ya think?
Ideas?

If you waited any time (5+ minutes) on one of the ovens it adds one 'tick'.

Your best bet is just using the fuel bug, you won't burn food.

It's possible in other batches I could have had time in between putting the dough in but this one for sure I had the sticks ready before I started so it was less than a minute to walk from one to the other and fill them. It's possible this oven is cursed and I'll just tear it down and start over

What is the fuel bug?

The short version: The timer for things in the smelter/kiln/oven begins as soon as the object is put inside, not when the fire is lit.
