Create: Power Loader works with create 6.0+ as it seems, but the steam engines hands don`t seem to move, even when everything is done correctly. I had a LVL 9 steam boiler working and after installing the mod with version "create_power_loader 2.0.0-mc1.20.1" with create version "create-1.20.1-6.0.4.jar" they just stop. Uninstalling the mod and replacing one block of fluid tank makes the boiler work again. Tried this too with the mod reinstalled and just refuses to work. Not sure if this is the cause, becase I have some create addons together with this one like for example Create confectionery, Create diesel generators and so on.

Create: Power Loader is most likely not the cause because it doesn't interact with boilers in any way. Please re-open this issue if you can reproduce the issue with just Create and Create: Power Loader installed.
