Which ships are spawning when this happens? Can you paste a link to the full log? (Pastebin etc)

I removed the Reddit ships and it hasn't happened again. My understanding(possibly wrong) is that the logs are rewritten each time the game reloads so I don't have a crash to submit. It was a "Supply Transport" IIRC. Sorry I can't give much more than that. I'm guessing it's not a common problem though or you'd have heard about it before

I pushed an update that should stop the crashing. Not entirely sure where it's originating from still, but it should be suppressed regardless.

Cool, I love the mod btw. Thanks for the help!

If it's not too much trouble, keep an eye on the logs. I've gotten it to spit out some data if an error happens. If you see any of those messages, can you forward them here?

Sounds good. I renabled the Reddit ships and have had zero crashes so far. You rock!

Im getting crashes a lot with my saves. i usually wind back up to the last good backup, but tends to lose a lil progress.

heres the tail of the log it gives me. I tested with turning the reddit ships mod off, but still get the crashes.

I'm getting the same issue, had it 4 times in a row, tested it with just the Modular Spawner + Corruption mod, and with a whole bunch of other cargo mods.

Log from crash:

In case it's useful here's the world, you load in on a ship flying straight forward. You don't need to do anything other than wait a short while for a spawn, and instant crash.

I'm getting a problem like this too...
I will post a Pastebin link when it does happen, which it normally does after 10 mins.

Well, It crashed

I have a new crash, that may be instigated by one of two mods if it isn't this mod's fault: https://pastebin.com/3XGsvSKb
I am sending the link to the log to them as well just in case, but I would like your opinion on it as well. My main suspects are ARMCO and whatever gave my modpack whiplash's railgun. Looking into it now.
