Running `setSchedule({})` on a station bricks the entire world

[Brainstorm4266]

Describe the Bug

When I ran, in ComputerCraft, setSchedule({}) (well, I tried to remove the schedule), the dedicated server crashed. When I tried to restart the server, it crashed again. And again. Aaaaand again.

Reproduction Steps

1. Place a station.
2. Connect a ComputerCraft: Tweaked computer to it. (Place one next to it).
3. Mount it as a peripheral using peripheral.wrap
4. Make sure a train is at the station.
5. Run station.setSchedule({})

Expected Result

Honestly, I either expected it to error, or for the schedule to be removed.

Looking at the error, it's possible that in the class com.simibubi.create.content.trains.schedule.ScheduleRuntime.handler method startCustomInstruction, the mod is trying to get a nonexistent index from the schedule, resulting in a crash (specifically at ScheduleRuntime.java:1055).

I can confirm this, for anyone trying to rescue their world, I "fixed" it by removing the data/create_tracks.dat file in the world folder. I think this will remove all trains and the tracks need to be updated.

[jojotastic777]

The same crash happens when you do station.setSchedule({ cyclic = false, entries = {} }) instead of just station.setSchedule({}).

[Shibva]

my 2 cents are that the method being reference is not properly accounting for the size of the array; in jojo's case, its when the list is empty and creates and out-of-bounds error. The method itself is not being handled correctly or has any sort of "failsafe" to prevent this crash from happening when the set or get of the sqedule is an empty array

[marcin212]

To fix your world, you can use NBTExplorer to remove the schedule from the train from the data/create_tracks.dat file: I fixed my game save this way.

[ThatMightyGuy]

I'm getting the same behavior on 1.20.1 when setting the schedule to throttle with a delay condition.
