Extreme lag when players join

[Arcturus]

I've been experiencing this ever since V19 came out.
Everytime a client joins my server, the server lags out, then blockland crashes.
Its only crashed 2 times, but im not sure if it will happen again.

This is v18/v19's fault. When a player connects, the server goes through every add-on you have enabled, and generates a file manifest and sends it to the player so that they can download it. If you have a few add-ons enabled, you almost don't notice it. If you have many add-ons enabled, you freeze for a bit. If you have very many add-ons enabled, you almost crash. A way to see this is that when people join, the last thing shown in console before the freeze is "Generating file manifest".

When people join, just wait until the game finished generating file manifest, or disable some add-ons when starting a server.

This happens to me, too.

Thanks.
