Describe the bug

Server crashes when opening a advanced importer/exporter and sometimes when opening a Wireless Grid.

How can we reproduce this bug or crash?

Play the game?!

What Minecraft version is this happening on?

Minecraft 1.21.1

What NeoForge or Fabric version is this happening on?

21.1.172

What Refined Storage version is this happening on?

2.0.0-beta 10

What modpack and modpack version, if any, are you using?

FTB Presents Direwolf20 1.21 v1.14.2

Relevant log output

Downgraded the server to RS v 2.0.0-beta2 and the crashes stopped. The RS cable is sometime showing incorrectly and the RS controller is still flashing blue and red.

1. In a bug report, if you mention a crash, you should link or bundle the crash report. Especially if there is a field asking you for it.
2. Instead of downgrading Refined Storage, try upgrading the addons. Especially if your crash is about an addon (advanced importer/exporter), and not Refined Storage itself.

Thanks for the advice. Upgraded the add-on and the server is running fine.
