This issue is one of those we just can't reproduce, we know it happens from time to time but all tests around it have failed to show us something concrete.
We had multiple bug reports in the past about it, latest one is
T1278 Transporter names, wireless logic and other data sometimes reset
It's most likely caused by some issue on saving or loading a sector.
It was part of a bug fix on
T1147 Unable to modify shipyard designs where core is enclosed in blocks, it's not closed yet since you can still get stuck upon leaving the ship now.
