Hey guys im not sure if this is just the one off but i was just there making some collectors and the server had a massive lag spike and when i backed out of my crafting bench the materials i was using just suddenly vanished into thin air so i waited around 10 min to see if they come back and so i began to test if the lag was still there by mining and nothing was dropping i went back t the spot where my items dropped and still nothing was there i even checked my inventory to see if i was being stupid and nothing.
I don't really care about the materials i used i just want you guys to be aware of what just happened so it doesn't ever happen to anyone else

Thanks for reading guys :d
Have a great day!
