Love the concept, haven't got it to work so far (specifically the fuel setup - trains never go to the fuel station even though the checkbox for external fuel is ticked)

anyway, I just clicked the toggle on a train for setting it to automatic instead of manual schedule, and it crashed.

This is a K2SO run.

The mod Railwave (0.1.4) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event railwave::on_nth_tick(1)

I deleted all my trains and recreated them after this, and now everything is working (fuel supply etc too)

actually I get deepcopy exceptions any time you modify a train that is already managed by railwave.
eg: have a train with layout LC1 sitting at a depot, then add a 2nd carriage to it. crash.

if this was on github i'd make a pull request, but the fix wasn't complicated since there was only 1 deepcopy in the codebase. (copy_temporary_schedule_records)

thanks for the awesome mod, I think it fills a really empty space in train management

Thank you for the detailed report. I was able to replicate it, and hopefully I fixed it.
try 0.1.5
