[03:18:14] [Client thread/WARN] [ArchaicFix]: Something (likely another mod) has attempted to modify the world's state from the wrong thread!
This is bad practice and can cause severe issues in your game. Phosphor has done as best as it can to mitigate this violation, but it may negatively impact performance or introduce stalls.
In a future release, this violation may result in a hard crash instead of the current soft warning. You should report this issue to our issue tracker with the following stacktrace information.
(If you are aware you have misbehaving mods and cannot resolve this issue, you can safely disable this warning by setting enable_illegal_thread_access_warnings to false in Phosphor's configuration file for the time being.)
java.lang.IllegalAccessException: World is owned by 'Server thread' (ID: 89), but was accessed from thread 'Client thread' (ID: 1)

It can also completely mute your game too. Sometimes it grants this crash also which is a bit inconsistent to always replicate promptly, sometimes when immediately spawning in, sometimes spawning in a few "Rainbour", but not always immediately. This issue is still there when phosphor is disabled within the config.
