As far as I can tell, the neighboring screen blocks fight over the opposite corner, crashing the game (don't know if this is helpful)

Thanks for the report, this is a known problem

In some cases they break and get not rebuild #10

There are some issues i wannt to solve before this (networking, compute nodes) but i added it to the 1.16 port project

More details: This happens only when the master node gets broken (bottom left)
