I looked everywhere around deep oceans and didn't encounter a single whale. Where can i find them?

Deep oceans/Deep cold oceans (some variants can generate in deep lukewarm, or non-deep oceans), but they are rare. You can also set "freqOcean" to a lower value in the config to get more Ocean spawns

Now that's another thing, post version and which mods you are running

It's also the kind of thing where Minecraft should complain in the console with a log, post it if you have it

I have exotic birds,citadel, bettas, farmer's delight, patchouli and oğtifine discluding untamed wilds. I'm using 1.19.2 in an aternos server. I checked the console and i dont see any new additions about that
