Null Pointer crash every time we try to play LAN after last update

Since these last updates whenever we try to start a game in LAN it crashes as soon as it loads. Crashes at the same time on three different computers with different maps and no mods.

I'd love to get some help with this. I've been playing this game since it came out on disk years ago.

Here's the summary of the memory dump from WinDbg, it's pretty much the same on all three computers:

Hello,

Sorry to hear you are having trouble.

If you go to:

\Documents\My Games\Ironclad Games

rename: Sins of a Solar Empire Rebellion

to: Sins of a Solar Empire Rebellion-OLD

Try to run the game again.

Hi Fulano,

I've been investigating the crash you reported. I wasn't able to reproduce it on my end but I was able to find the proximate cause thanks to your excellent bug report. I'd like to gather some additional info to help narrow down the root cause.

Which platform (Steam, GoG, Xbox) are you playing on?
In your attempts, how many human and computer players were in each lobby?
Does the crash occur if you start a game on the "The Void" map?

If you're curious, or in case it rings a bell, here's what I've discovered about the crash so far:

The crash occurs because a "squad owner" (a unit or structure that builds strikecraft squadrons) is being created without a valid owning player. Squad owners periodically check whether they're owned by an AI player to decide if they should auto-build strikecraft. Since the squad owner doesn't have a valid owning player, the game crashes when performing this check.

I asked whether the game crashes on The Void in particular because that map doesn't have any preplaced squad owners, whereas most maps do in the form of Pirate Hangar Defenses. I'd be surprised if the issue were isolated to just squad owners, but at a minimum it'll crash at a different spot and shed some further light on the problem.

Sweet, thanks!

Hopefully I get some time in the next two days to do some more testing for you.

I'm running Windows 10, playing on Steam, we had three players, and I think we tried it with just two players, but my memory is fuzzy right now. We usually do an "us three vs AI's" in comp stomp maps that I make in galaxy forge when we've played in the past.

I don't know what is going on here...

I got two of the computers fired up, tried The Void, and it worked.

I tried the Galaxy Forge map we were originally trying, and it crashed without even doing the mini-dump on my computer, but the second computer loaded it fine.

I loaded the map in single player on my computer and it worked.

I tried some other maps of all three types (Galaxy Forge, Map Designer, and Default maps). They worked.

I looked at the map in Galaxy Forge again to see if somehow I had some hangers spawning or something that would cause the bug mentioned above, but didn't see anything.

Sooo I got the third computer going and tried that Galaxy Forge map and it worked...

I re-enabled the E4X mod and it worked...

So ya, I don't know what happened, it's like loading a different map reset something?

Let me know if you want me to do some more testing. I have had LAN games get to a certain point and crash, even when re-loaded. If that happens again I'll send a report (assuming I get a memory dump...)

How odd, but it's good that you're able to get ingame now. To be clear, you're able to launch into a LAN game on the Galaxy Forge map?

If you do end up with a midgame crash - fingers crossed that you don't - I'd be pleased to investigate. In the meantime, happy comp stomping!

Ya, it's working normally all afternoon as far as I could tell, awesome that it's working, but a pain in trying to track down bugs.

Thanks for the help!
