Well, I was starting to make my first machine, the wood farm, and every time I tried to make any multi-block structure, the game crashed. I tried to use the cart assembler and the normal rotational force. (sorry for the english)

hs_err_pid14148.log

that's the default version of java that ships with minecraft, i think? I had good results using current adoptium at adoptium.net/?variant=openjdk8 or use whatever, just use something more current.

Thank's ! I'll try...
