hearthstone blows up

[WigWam]

so im trying to make a boat but my hearthstone blows up. is it getting too much power or getting too hot and if so how do i stop it

[TinyMuffinLord Who?]

try adding some batteries, ways to charge it and electric engines, that should fix it

[Takamiki]

depending on the size of your vehicle you may need to add extensions that increase the amount of blocks the heart stone supports

[Itching Pain]

I had to place the extensions for a heart stone first. then I was able to place one without it blowing up.

If your heart stone blows up while you are building your ship then it is not getting power. Probably you are building an engine but then forgetting to build a fuel tank. With no fuel the engine cannot run and it will not recharge the heart stone. It could be that you are running completely out of fuel in the fuel tank if you are running lots of stuff. In that case you need to remove your fuel tank and rebuild it so it will have fuel again.
