I noticed this with Blueprint Sandboxes (https://mods.factorio.com/mod/blueprint-sandboxes) but i assume the same will probably apply to any surface thats not a planet or space.
The Resulting error is:
Error MainLoop.cpp:1449: Exception at tick 8777166: The mod What Time Is It (1.0.2) caused a non-recoverable error.
Please report this error to the mod author.
