I'm going through my multi mc console output that I get on start up to see what errors are occurring to report them to the various mod makers. I noticed a few that I think are attributed to this mod. I'm on fabric 1.18.2 and my mod version is 0.8.5

First is some sound thing. I think it means that you forgot to add a sound effect file or something? Below is the line of the multi mc console output that is relevant.

[19:32:28] [Worker-Main-7/WARN]: File minecraft:sounds/entity/generic/splash.ogg does not exist, cannot add it to event crockpot:block.crock_pot_splash

Second, there seems to be multiple missing model variants, whatever that means. Relevant lines below.

Oh, these are warnings because I'm a dingus. The big WARN means it's a warning that won't crash the game, but may affect operation.

In this case, I'm still fiddling with trying to find the splash sound effect Minecraft has, and the model ones are because I have more block states being used by the block than there are model definitions. None of the block states that are missing affect rendering, and thus, it's totally okay.

Nothing to worry about, I'm just breaking conventions! haha
