That is, the game changes more lua libraries/functions than are listed at https://lua-api.factorio.com/latest/Libraries.html

One example I know of is the random.set_seed, whose "silent deletion" caused me unending headaches back in 2016 when I was designing Oreverhaul: viewtopic.php?f=25&t=34941&p=217395#p217550

I imagine this is not the only such missing function.

Reminder for future me: It's math.randomseed() which is deleted and math.random() which is changed to be deterministic.

The functions are now documented.
