This ticket is invalid as it relates to a modded or 3rd party client/server.

• Any non-standard client/server build needs to be taken up with the appropriate team, not Mojang.

• Any plugin issues need to be addressed to the plugin creator.

• This site is for addressing issues related to the base unmodded MineCraft.

1 - Not modded minecraft (only mod it's modloader ok?)
2 - It's not a plugin it's Single Player

Your Minecraft is modded:

Is Modded: Very likely; Jar signature invalidated

yes but?
The problem it's from minecraft! Not the mods!

If you can reproduce it in vanilla, we can reopen.

Except that unless you use a non-modified Minecraft there is no way for us to tell that with any certainty, so please reproduce without a modded Minecraft.

Also Minecraft doesn't obfuscate mixed upper/lowercase letters, so sorry, not a single penny of support here.

I'll try but I'm not sure because I have to be laggy and crash in a second. It's really hard to do it.

I think it's good now! Entered in the game and crashed.
