Crash after placing Adv Solar Panel

[kpoe112]

Minecraft version: 1.12.2
Galacticraft version: 4.0.1.121

Single player (SSP), Multiplayer (SMP), or SSP opened to LAN (LAN)?
Just playing in the single player client. Not open to LAN.

Galacticraft add-ons and other mods installed?
Yes. Nothing other than Galacticraft/mcdoodle8 loaded.

I was playing Galacticraft just fine for a while. I went to place my first Advanced Solar Panel and Minecraft became unresponsive. Closed it and tried to open up my saved game. Crashed. Now every time I try to open the saved game, It crashes. Below is the crash report. Not sure what happened or why. I just want to continue my game. Hoping it can be saved.

Your running a "bogus" version of the mod ie NOT official please download the correct files from here:

https://micdoodle8.com/mods/galacticraft/downloads

[radfast]

Where did you download this file from: Galacticraft-Mod-1.12.2.jar?

Maybe we should try to get them shut down.

[MJRLegends]

I'd strongly recommend adding jar signing as its a easy way to tell if they have compiled it themselves or downloaded a unofficial version. ExtraPlanets uses it for MC 1.8 to 1.12.2 versions @radfast

[kpoe112]

This is where I found it:
http://www.9minecraft.net/galacticraft-mod/

Thanks. I'll get the legit one now.

@kpoe112 I had the exact same problem, Minecraft stopped responding when I tried to place the advanced solar panel from Galacticraft Core so I closed it and when I tried loading that world it kept crashing..... So I was wondering if downloading the legit one solved the problem or not?

[TheQuadShot]

@RockyWafflez
Regardless, you should download Valid files from here: https://micdoodle8.com/mods/galacticraft/downloads
The answer is maybe?? If you need more help please post this in the support thread at the Forums Page here: https://forum.micdoodle8.com/index.php
Provide crash logs, and logs on pastebin/hastebin... and provide a link to them, as there MAY be a way to fix your world, but no guarantees though. Thanks

@TheQuadShot Thankyou, I did it and it fixed the problem and my world is fine.. yay
