if your blaze burner has liquid fuel reloading it causes it to lose all data (so if you fuel a burner with lava leave the world and rejoin it would have nothing in it)

same here with forge 1.20.1

i also found this line in my logs that is probably related "[15/07/2023 15:31:07 PM] [Server thread/ERROR] Failed to load data for block entity create:blaze_heater"

That shouldn't happen, which version is this?

1.18.2

forge

Fabric or forge?

Would it be possible to send me the full log of when this happens?

odd, I can't recreate this at all.

Hi, I got the same issue here. Every time I enter the world the steam engine is shut due to lack of fuel in the blaze burners and I have to re-initial the engine manually. My setup is pumping blazer blood (from tinkers construct) into the burner directly through the pump.

Sounds similar to my 1.19.2 Fabric.. When I shut down the server.. all the blaze burners are off whenever I start the server back up. There's tons of lava but the burners are all off. I have to pump the water into the tanks manually and then also manually pump the lava into the blaze burners to get things going again.... every time. No errors in the logs of any kind..

Out of curiosity, once your setups are running, are they designed to power the water and lava intake pumps using SU from the steam engines themselves or do they have separate power sources? If they are powered by the steam engine, as a test, can you add, say, a creative engine to power the pumps, restart the server, log back in and test?

I've not run into the issue you're describing with this mod, but I have had, let's say, more weirdness with the "steam engine powers its own pumps" scenario than I have with "steam engine pumps are independently powered" scenario.

my setup was designed to power itself yes

The real issue is that the liquid fuel in burner after restarting the game would disappear. If your fuel is powered from another source, then the fuel loss would not matter at all, since other source would send new fuel in. But if the burner is self-powered, the engine would not work due to lack of fuel which is unintentionally caused by restarting game.
