This machine failed memtester, so the report is useless.

Nope, server was not mine, and it is gone now.

Also topic title is incorrect, it should be "Crash of client", not "Crash of server", since server autosaved without crashes, but clients could not save local copy.

My bad. The game allows to place signals manually if you do it 1,2,3,4, but does not allow if you do it 4,3,2,1

There are two rails near this signals, curved and straight. I dont expect this case to work as it is looking, this signals are probably not attached to curved rail.

Personally, I would expect default lamps to be treated as single entity, similar to solar panels. If that is not the case, maybe create a world covered with lamps, and submit it here Performance optimization - post your saves.

When finite deconstruction order disappears from a tree/rock that blocks infinite construction order, robots are stuck flying over the ghost.
It clearly violates player expectation at least.
