Describe the bug

When attempting to boot with Create Railways Navigator, Seamless Loading Screen and Sinytra Connector, the mixin from YACL on ContainerEventHandler fails to apply and crashes pre-modload.

Steps to reproduce

When the following mods are installed, the game crashes on startup.

Mods used to replicate:

• Sinytra Connector 1.0.0 beta 44
• Forgified Fabric API 0.9.22+1.11.8+1.20.1
• Create 0.5.1f
• Create Railways Navigator 1.20.1-0.5.4
• Seamless Loading Screen 2.0.3

.connector/ folder was cleared before verification.

Additional context

⚠️ This issue ONLY occurs when ALL mods are present. No Fabric mods or YACL need to be installed for this to occur. Tested combinations of:

• RailNav + Seamless
• Seamless XOR RailNav + Sinytra
• Seamless + Create only + Sinytra

all booted properly.

Environment details:

• Forge 47.3.1 - 1.20.1

Please let me know if any further information or other action is required, and if I should post this to the relevant mod repos.

Does this occur without Connector installed? According to the log, a conflict occurs between mods YACL and mcdragonlib.

[Alexander3847575]

It does not, weirdly enough. mcdragonlib is an internal library in Railways Navigator, and I'm not sure where YACL is coming from. You can see my tested mod combinations under the Additional Context section; all done in the provided environment. As stated, the issue only occurs with all three mods present.
