950K block ship, single reactor, retrofitted from old power, all old power modules removed.
96,067 reactor blocks.
96,066 stabilizer blocks.
Sufficient distance, around 250m minimum to closest stabilizers from reactor.
Showed 100% stabilization at that range previously.
Now showing ~14% stabilization, and wants minimum 897.5m distance to stabilizers from reactors.
The reactors were originally made in six 16,000 reactor chunks and connected together. If I chop them apart, the minimum distance drops down to 617m, 96.3% stabilization.
