so i have been playing for a few hours now without problems but suddenly past a certain point now, i keep getting crashes and fatal null errors that i dont completly understand
the game was doing fine, and it happens just travelling in a system or the hyperspace, and even loading some recently older saves is still making the same error again! for some reason, i dont get it, on why it sudedenly started happening.

- here is a snip of the log

Only tested my latest save file though. It always happens a bit after I beat one Legio Raid, and MVS sends another raid (they're allied)
not sure if that's relevant but those are the only consistent things that I can mark before my game crashes.

Did you guys recently update any mods?

Did you guys recently update any mods?

Not for me. I was actually thinking that updating some mods might fix this.

EDIT:
Tried updating magiclib
now I get the same exact error log as OP

The curious thing is that the call stack is entirely from the game API without any mod method calls.

The error itself relates to an ArrayList being modified while it's being iterated.  It could either be the result of using the wrong type of loop being used or a multi-thread concurrency issue. 

It could be that a mod is modifying the ArrayList from another thread, and either the mod or the game itself haven't declared it to be a synchronizedList.

Considering the call stack, this may actually be something for Alex to take a look at.

[Naimod]

here's hoping there's a fix. I just got into peak enjoyment on my current save

[float]

There's a good chance that some mod is trying to remove a market condition via removeCondition inside a loop over that market's conditions. The error isn't caught until the next time the conditions list is iterated over, which happens to happen in the base game code.

If that’s the case, it could be AI retrofits. It lets you build colonies that are essentially ran by robots. It kind of messes with the usual demands of industries.

But it could be other mods as well like Industrial revolution.

Yes, I think there's a very good chance that it's either from that mod or its MarketRetrofits dependency.  You should post a bug report in one of those threads and remind Alaric that it's not possible to either remove or modify elements from within an enhanced for loop.

HMM, well those are some really nice insights thank you,tho  it doesnt seem ai retrofit like a mod that can be removed and keep playing normally on that save if thats the case...wich is a shame i suppose, guess i might try another game for a bit i will try and if it happens again i will take it out, i kinda want to use it a lot but if its really the problem i will just go without it

if the problem is only with the market aspect of the mod then you might still be able to play with the hullmods and crewreplacers. You just have to abstain from building the automated colonies.
Did you build any?

I did, didn't have an issue until I built a 2nd one.

[kur0pur0]

well, i havent actually done any colonies with it, just some ships, my first thought maybe the AI made one but now that i think so, maybe its not that huh.

[Histidine]

I think TASC also has at least one condition that can be removed while it's being applied, although I don't know if this has been linked to any such crashes.

Anyway in Starsector 0.96 this particular issue won't happen.
