When I use schematica I upload a schematic and press print. It looks like it is placing it but then doesn't place anything. It doesn't crash my Minecraft or anything.

Im in creative on my server as well.

I fixed it BUT it crashes after doing about 10 blocks. It says sending too many packets. How to fix that?

ALL FIXED! It was a viaversion problem! Just turn max-pps and the one below that to -1!

SO ANOTHER PROBLEM! It places the blocks but it doesn't actually place them. BASICALLY, it shows there placed but when i go off and go back on its ALL gone!

FIXED! HAD TO TURN ADJACENT BLOCK TO TRUE AS IM USING 1.8+!

ANOTHER PROBLEM! I built it and then saved the world and went off my server and then I went back on and some blocks (about 200 out of 40,000) were missing so I filled them in and went offline again and I came back and a different approx 200 blocks were missing again! HOW DO I FIX THIS?!

Why the heck did you tag me?? I don't believe I'm mentioned as staff and I only made a minor pull request over 5 years ago...

@Tatara88 It says ur staff on @

That is a desync issue and I'm not sure what could be done to fix that, other that making the printer go slower. That usually prevents it, but not 100% of the time. It seems to be something with the server validating your block placements.

I have slowed the printer down. I will keep this issue updated if it does/doesn't work.

UPDATE: Workes fine now. Thanks
