Totally broken and log spam.

Minimal instance. All I did was launch the game and then quit it.

For example:

Exception loading blockstate definition: 'mcwbiomesoplenty:blockstates/dead_log_bridge_middle.json' in resourcepack: 'fabric' for variant: 'connection=end_e_toggled': Unknown blockstate property: 'connection'

Exception loading blockstate definition: 'mcwbiomesoplenty:blockstates/rope_dead_bridge.json' in resourcepack: 'fabric' for variant: 'facing=east,connection=middle_end_n': Unknown blockstate property: 'facing'

latest.log

Minecraft 1.20.1
Fabric

When you click 'Singleplayer' you see even more issues such as
Parsing error loading recipe mcwbiomesoplenty:jacaranda_window2 com.google.gson.JsonSyntaxException: Unknown item 'mcwwindows:window_half_bar_base'

Here's another example:

For the spam you have two solutions.

1. Obtain assets from various Macaw's Mods that you don't have to create a resource pack (addons are based on the original Macaw's Mods models)
2. Install LogBegone for delete all spam.
