[2.0.73] Attacking biters while cease fire set

[burninghey]

What did you do?

Install the Mod https://mods.factorio.com/mod/Parley then did /parley in console to trigger set_cease_fire (it's here what it does: https://github.com/StargateurFactorioMo ... ontrol.lua )

What happened?

Biters are friendly now, they have no problem with getting overrun by trains or being shot at. I can shoot them in close contact with the handheld flamethrower too and they stay harmless until dying. Their acid doesnt damage and they are not allowed to attack any structures or the player character.

But .. every once in a while I'm loosing a train or part of a train due to angry biters:

When they group up for the next attack (or expansion?) they are a lot more alert and aggro. Try to burn them or running a train through the group turns them into real enemies now. They still cant touch walls but they are happy to hunt the player or the train now. Spitters try attacking but their acid doesnt burn. I'm loosing parts of trains and sometimes (very rarely) even gates or turrets.

What did you expect to happen instead? It might be obvious to you, but do it anyway!

No train or infrastructure losses while peaceful biters peace active through cease fire. If anything, their behaviour should be a lot more consistent. Either can't kill anything or hunt attackers down but not a mix and especially not differences between worms unable to damage with acid and biters able to kill things.

Does it happen always, once, or sometimes?

Always, when another group forms near my rails and a train drives thru.

I have attached a savegame with the biter group just killed another rail wagon. Look at the latest alert at Nauvis. You may load it without any mods, it doesnt matter. The aforementioned mod isnt in the mod list either, as i used it to trigger the behaviour once and then removed it.

Thought it was the mod's fault first. I noticed loosing trains many times and tried to workaround with more walls. Then learned it triggers a common factorio function which seems to behave defective under some circumstances.

The biters already created when the ceasefire is changed are not affected, the mod should update them or kill them all.
This includes commands like build base, attacks from pollution, etc.

Or perhaps it is something else, if you can recreate a setup where they are definitely meant to be peaceful but still attack, we can look at it
