rigth click on the testitem in the slot 5 get error cath cachit and set a ramdom value for it "839" the value "433" in testitem slot 3 is not afected


the same goes for the one in the sloth 9 it  gets "127"

worldIn.playSoundAtEntity(playerIn, "modmercenario:run", 1.0F, 1.0F);


try {

NBTTagCompound exi= testitem.getTagCompound();

int ex=exi.getInteger("gearbox");

System.out.println("contenido de nbttag gearbox ="+exi.getInteger("gearbox") );


} catch (Throwable any) {

    • I am in such a mess. I have lost over 4.7m due to a scammer... It started as bank wires and then bitcoin. it is hard to imagine but it is true and can send any proof, then I tried to use a couple of recovery companies and was as well. Graphic design has been more than just a hobby for me since high school—it has become a thriving career. Starting in my parents' garage, I eventually expanded to my office, running a successful graphic design business. However, like many, I faced the need to diversify my investments due to inflation. This led me to invest 60.16 in Bitcoin, a decision that paid off handsomely as my investment grew to 4.7m over time. This financial windfall allowed me to upgrade my equipment and take on more ambitious projects, furthering the growth of my business. Unfortunately, my excitement was abruptly cut short when I fell victim to a hacking incident. Malware infected my computer, giving hackers access to my Bitcoin wallet. The devastation of potentially losing all my hard-earned savings and plans weighed heavily on me. At this dire moment, a fellow designer suggested Linux Cyber Security Company as a potential solution. Desperate for a lifeline, I reached out to them, hoping for a miracle. The response from Linux Cyber Security Company was prompt, incredibly professional, and effective. Their team quickly traced the hacker’s activities and recovered most of my funds, alleviating a significant amount of stress and uncertainty. Beyond the recovery, they took the time to educate me on essential practices to secure my Bitcoin holdings better. They emphasized using antivirus software to prevent malware infections, avoiding suspicious downloads, and the added security provided by hardware wallets. This experience served as a critical wake-up call for me. It highlighted the vulnerabilities inherent in digital assets and underscored the importance of robust security measures. Thanks to the guidance and expertise of Linux Cyber Security Company, I now feel more equipped to protect my digital assets proactively. Their insights have empowered me to implement stronger security protocols in my business operations and personal finances alike. With my Bitcoin funds securely recovered and a newfound understanding of digital security best practices, I am more confident in navigating future challenges. This journey has reinforced my commitment to safeguarding my hard-earned assets and leveraging technology responsibly. I am optimistic about the growth opportunities ahead, creatively in graphic design and prudently in investment strategies. In conclusion, while the hacking incident was a setback, it ultimately became a catalyst for enhancing my digital security awareness and resilience. I am grateful to Linux Cyber Security Company for their expertise and support during a challenging time, enabling me to continue pursuing my passion for graphic design with renewed confidence and financial stability. Contact a professional company I am sure they can help you with your case too, Website [www.linuxcybersecurity.com Email the team; info@)(linuxcybersecurity.com
