[Bug]: Using this modpack in crafty controller spits out this error

[dovjonu]

Possible Fixes

Yes

Modpack Version

2.22 (one mod that has been modified, was kubejs, because it kept crashing while turning on prior to changing the mod)

What happened?

Crafty controller software is polling the server very often and Connectivity mod is not happy about it. I found an issue in the Connectivity github for the same problem, and it was answered as the problem of AllTheMods 10 and not Connectivity. I have also reached out to Crafty Controller support, and they said that polling a server for information is normal, they might do it more often that others, but it's not their issue.

Here is an error that is repeating every second or so:

Together with crafty developers we figured out that it's the problem of Better Compatibility Checker mod, current fix is removing Better Compatibility Checker from server-side.
