The mob spawn rates make your Snapshot servers disgustingly unplayable.

Quick FAQ before I post this, so none of the mods give the generic responses...

Q: It's because they're snapshots. They're experimental.

A: No, that's not the reason. Nobody has reported this bug yet, and I spent several hours both today and yesterday searching for others with the same issue to find a solution. This is a behaviour I have observed exclusively in your servers. It's not Mojang.

Q: It's your render distance.

A: Nope. We all have our render distances at 12 or higher.

With that out of the way, here's the problem...

Running a server on 19w11b. My friends are all slightly jaded to Minecraft, and I proposed we run the newest snapshots to convince them to play. They agreed, and we've been having fun, but mobs hardly exist.

gamerule domobspawning is true.

difficulty is on hard.

we've ventured very far from home on multiple occasions.

i have never seen a spider, and i need string.

Mobs still spawn, but trying to find one is like trying to piss into a shot glass strapped to a running cheetah's back blindfolded, trying to keep your concentration while a centipede crawls on your face.

I've observed a few other people make a similar complaint about your 1.13.2 servers, to which all the responses I've seen are "use a plugin to increase mob spawn rates, we don't know why this happens."

But that simply isn't good enough. There needs to be a solution.

I get the feeling this has to do with the new way 1.14 handles chunk loading, but that is just my guess. This is a ridiculously broken issue that needs the immediate attention of your staff. It affects vanilla, and should be frontline priority to be looked into.

And one more FAQ before I end it off.

Q: Roll back to 1.13.2

A: As stated, it appears a similar issue persists there, and my friends are already in love with the new villager features, pandas, utilities and overhauled textures. 1.14 is massive, and everything added has been a net positive for them. From experience playing games with them, I know their enthusiasm for a game is fragile and unstable, and can easily drop off, and as such, I fear stealing these beloved features from them may make them lose interest in the game, and force the world to be dropped on day 2.

Hopefully this can be looked into, and an actual honest solution can be presented. There is no excuse for this to be swiped under the rug.

Thanks!
I'll let you know if the problem persists.

Well, it appears there has definitely been a slight improvement, but it's still not great, Roman.

Immediately after the server went active, I spotted a creeper on a hill, I thought "Hey, it seems to work now!" but that was quickly shot down, actually.

I decided to switch to Creative and fly around to verify if the problem was indeed fixed.

Not a single mob spotted on this flight, however, coming back to the spot where I logged in, I noticed a skeleton had spawned next to the creeper I discovered earlier, and three zombies were in the forest nearby to it.

I also discovered my very first spider in that forest.

Edit: I idled for two separate nights in the same spot (a new spot, but i was there both nights), no more mob spawns.

Seems the issue still persists.

Edit Edit: Nope, actually, there are a cluster of mobs nearby.

Still, the issue could use some further optimization. Thanks for working with me on this btw!

Have you heard about the chunk errors? If not, I'll explain it, but if you've heard about it, that saves me quite a complex explanation.

Essentially, our group is locked on an island. Not literally, but figuratively.

If we travel about ten chunks out in any direction, we encounter a chunk error that can take upwards of an hour to absolve. This happens in the nether as well, with up to only 6 chunks total being able to load at a time.
