I use McProhosting with friend to play with a personal made modpack and the newest version of create is on it. 1.19.2 / 0.5.1.b

Whenever I leave the base that has the steam engine and the chunks get unloaded for a few second the Engine just stops working and i have to start it again

this is not a bug. unloading breaks loads of things that depend on updates. it is often recommended that pumps be powered by e.g. waterwheels, so they fix themselves when they get reloaded. personally i run a quad lvl 9 steam engine power plant that self powers its pumps and it has never had issues with unloading... so perhaps size matters ahem...

i do have a quad lvl 9 engine that also auto power the pump, but damn alr that sucks tho, built a max lvl windmill for the time we dont use the chunks where the steam engine is either way

you could use a chunk loader

either way, please remember to close the issue
