B9partswitch ksp fatal error

I don’t think it’s really fatal. I usually ignore them. Updates normally fix them.

Apologies the button usually says “OK” when it happens to me, not “Quit”.

How do I ignore them? It’s either play with that text box on the screen, or quit the game.

Yeah Ive never not had that b9 part switch failure lmao

B9 Fatal Error means «click me and close KSP.» What you’re describing are «B9 Serious Warning»

Open the ksp.log file, hit ctrl F search for fatal error. The log will tell you what part is causing the problem and why it is a problem

It’s the version for 1.10, which is what I play on. Guess I’ll have to go without, sucks since I lose all the near future and space station parts.

Download more mods it will fix itself

what did you update right before the error showed up? its almost always due to the change you made right before the error started happening. (this is true in general with computers, not just with Kerbal.)

I downloaded all my mods, loaded the game, and got the error. The only update regarding KSP I did, was changing the version back to 1.10 and verifying the game files.

I’m sorry off topic but is the mission builder a DLC or something? Maybe a new update? It’s been a bit since I played

Do what i do and ignore all the warnings telling me my game is about to implode, it never does

What mods do you have installed? Do you have any life support mods installed?

Mod authors generally prefer a mod list and a copy of the KSP log.

I’ll see what I can find out for you:

@WranglerOfTheTards27 I created a post for your issue on the KSP forums here.

Directions to get help with mods

I’d like to see your KSP.log, your Logs/ModuleManager/ModuleManager.log and your GameData/ModuleManager.ConfigCache (preferrably all in one zip). I’m sure I’ll spot the source of the error.

Try using the 1.11 version of B9PartSwitch with all the mods you intend to use. Coincidentally, I installed B9PartSwitch as a dependency for Near Future Solar, Near Future Spacecraft, and SSPEx all for 1.11 today and it worked like a charm even with ReStock, Waterfall and a smattering of other visual mods.

Does the 1.11 version work with 1.10? The main mods I have haven’t been updated to 1.11 yet.

It’s warning of configuration errors on various parts that use B9PartSwitch. These were all issues previously, the change is that it’s displaying the dialog with them rather than just dumping them to the log. These are all coming from Near Future Construction, I believe Nertea is working of fixing them. Until that happens you can just click through it though — it’s not like any of this was working before anyway. But if you install additional mods and see additional warnings it might be worth looking into them so that the respective mod authors can be alerted.
