welcome to the club there!
same issue here

p.s. some one pushed wrong branch to steam?

Hello everyone.
Do you run the server with shard ID from 000 - 099? As doing so will result in such error.
Using shard ID such as 111 will resolve the problem.

It was also mentioned in the changelog:

Changed: Attempting to start a server with ShardIds 000 - 099 will prevent the server from starting up, as those are reserved for official servers

The shardid parameter is part of the server config.

serverDZ.cfg

shardId = 111 (example)

That worked. Thanks a lot Geez ❤

Glad to hear <3

I just wasted an hour over this....

Please add this to the patch notes and the serverDZ example included

How could anyone not have understood that it's a serverdz parameter from this? We're expected to just know what shardids are and how to apply them from this????

Agreed this wasnt the best way to communicate this change, if possible it would be nice to edit the changelog, especially since this is a required change

Yes, it's not very clear inside the changelog. Can you say whether the "shardId" must be unique for each server hosted on a machine? Apparently, the same shardId can be used. But this is not clear without documentation.

Perhaps it would be a good idea to ensure that servers without a "shardId" in ServerDZ.cfg can start up without crashing. Many people are likely to complain about this when version 1.26 becomes stable, so it would be better to anticipate and avoid these problems.
