So, I have been trying to follow the online youtube resources to add a custom loading screen to my server, but they are a bit out of date from a year or longer ago. I have been giving it a go for the past few days by trying it through making the "loadingscreen" mod, packing my own pbo, getting everything signed, puiblished and just can't get it to show up when logging in. I would assume these videos are from version 1.21 moding, but how can I do this in 1.22? The server and client seem happy with the pbo I made and it's not giving me any errors on either side, I just can't get it to load. Any insight? Would it be better to try and find it in the server pbo files and replacing it from there, or would that set off the battle eye system? Thanks for any thoughts.

I'm looking for a way to keep some items in my types files from not spawning in the world, but I want them to be bought through the trader. What values in the types file can I change? Nominal to "0" and Min to "0"? I also have some items like the ammo boxes, I just don't want them to spawn in the world and I'm not making them available through the trader, can I just delete them from the types file all together without ill effects or should I use the Nominal "0" Min "0"? Thanks!
