Bug MC 1.21.0 Sawmill 1.5.0 conflict with Remove Reloading Screen

[kingstairs]

I am setting up a Fabulously Optimized (6.0.0-beta.6 for 1.21.0) instance. When Sawmill is active, you cannot create new worlds or launch existing ones - Minecraft seems to lock up. Not sure what it's actually doing. Problem is reproducible.

Testing with newest Fabric loader and API.

I did test this with a minimal Vanilla 1.21.0 instance (Fabric API, Moonlight, Sawmill only) without issues, so there must be some conflict with another mod, or possibly something in Moonlight (2.14.12).

One thing I did notice:

• With Sawmill disabled, when creating a new world the log has lines for recipes loaded (2297) and advancements loaded (2138).
• With Sawmill enabled, the log shows "Waiting for tags", and advancements loaded (2139) - there is no recipes loaded log entry.
• There are no Sawmill-related log entries (warnings, errors, etc.)

I'm going to spend a little time this morning trying to identify which mod might be conflicting.

It's actually Sawmill 1.5.0 - in Prism it's reporting itself as 1.4.4, so that's another bug...

And I found the source of the conflict - Remove Reloading Screen v5.0.1 with Sawmill 1.5.0 triggers the problem.
Here is a minimal mod list demonstrating the issue:

1. Cloth Config 15.0.128 (for RRS)
2. Fabric API 0.102.0
3. Moonlight Lib 2.14.12
4. Remove Reloading Screen 5.0.1
5. Universal Sawmill 1.5.0

I updated RRS to the current 5.0.7 release and it looks like the problem disappears (at least when creating new worlds). I'm wondering if RRS is conflicting with something Moonlight might be doing.

Hopefully that will give you enough information.

Maybe I could mark it as incompatible. Don't have time to see where actual issue is
