Hello! Alex's Mobs and the other mods made by Alex-the-666 looked awesome, so I placed a bunch of them on one MultiMC modded 1.16.5 Forge instance. I'm testing how well this instance runs before trying to put together a modded Forge 1.16.5 Minecraft server for my friends.

Current Issue: The log shows a lot of yellow WARN errors and one red error and they look concerning. Some mention not being able to find sound or texture files. The red error mentions not being able to find the model of the blood gun.

Past issues: Before at some point, I've also had to downgrade from JDK 16 to JDK 11 and then adjust MultiMC's settings to point all instances at the JDK 11 Javaw.exe file, otherwise there would be a load of yellow AND red errors and crashing. I don't have the logs for this unfortunately.

Additional notes: The game runs and does NOT crash. It only crashes when I have the FallingTree mod enabled.

I've copypasted the whole error log of the current issue onto this pastebin link here:

Thanks in advance and please let me know if there's anything I should do!
