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 ♥♥♥♥♥♥ 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.
