Anytime I try to start a server, it crashes. Client works fine with other 59 mods. First I tried to start a server with about 50 mods, but it kept crashing. Then I tried to launch it with only Tiny Progressions 4.0.0 but problem still persists. Here's a log. https://pastebin.com/XriSy3xW

The block that originally caused the issue is still not fixed atm. That's why it was removed from game for now.

So is this fixed?

Thank you for the report. I will take a look at it. This is beta so I was expecting bugs.. just thought server bugs were fixed.
