[Oxyd] [15.17] Client & Headless Client Crash

[AlienX]

Hi Devs,
Every client connected to the headless client, including the headless client crashed at exactly the same time.
Unsure what the cause was - and also unsure if the log will help, but i thought i would post the files anyways.

At the time of the crash, we were picking up belts which had items on with our personal robo ports.

Pathfinder bug of some sort, everyone in the game (including the server) crashed because everyone needed to run the pathfinder for determinism.

Code: Select all

EDIT: Can you provide the most recent autosave from before crashing, especially if it is reproducible?

I've since gone to bed now, however another guy who plays on the same server has said it's crashed again since restart.

I'll upload a save in the morning

i got ya bud.


Server crashes within 5 mins regardless if single player or running via server

[AlienX]

Tested on 15.17 - still crashes.

[AlienX]

I have a feeling that setting a LUAEntity type of "Unit" to entity.active = false causes this crash, code example below:

Code: Select all

for _, e in pairs(game.player.surface.find_entities_filtered{force = "enemy"}) do
	if e.type == "unit" then
		e.active = false
	end
end

Thanks, should be fixed in 0.15.19.
