I wanted to try your mode and at the same time installed the [url=https://mods.factorio.com/mod/trainConstructionSite] Train Construction Site mod[/url],
When I placed the first Trainbuilder block I got this error:
The mod How Far Has it Been? caused a non-recoverable error.
Please report this error to the mod author.
Error while running event howfardiditgo::on_nth_tick(30)
LuaTrain API call when LuaTrain was invalid.
stack traceback:

stack traceback:
[C]: in function 'index'
__howfardiditgo/control.lua:68: in function <howfardiditgo/control.lua:65>
Would you please look into it ?
