Same thing happened to me. Server hosted on a 3rd party website. Had an XP farm with a cobble generator, carpet generator, and furnaces. The system did not have a true "off" switch, rather only an auto-mode, and basically every time the reserves of supplies got low it would activate circuits and refresh them. 

I afk'ed for a little over an hour at a nearby creeper farm (no redstone) and when I came back I could not visit the chunk without crashing the server.

The same thing is happening to me and it is extremely annoying. I've lost a full set of enchanted diamond armor TWICE because the blaze will literally one shot me (only one of his bombs hit me) and the "armor breaking" sound played as well. Happened to me a week ago, thought it must've been a unique glitch, but just happened to me again and decided to look it up.

I am playing the latest version of MC PE, on iOS, on a hard difficulty survival realm. It's bad when the blaze is the single most powerful mod in the game. I'm not sure if any of my armor had fire protection, don't know if that affected it.

Youcef,
I am not using lava as fuel. This happens with regular coal.

To replicate this bug, fill up all 9 of your slots with items. Pay attention to make sure you would notice if they're missing.

Then put in items in 3 different furnaces, all cooking / smelting at the same time.
Then after a couple of minutes, clear the finished products from one furnace. Pay attention to your toolbar and don't move anything.
Clear another furnace, inspect toolbar again.
Clear third furnace and inspect again.

If you don't lose any items then we must be on different MC versions. It happens to me every day that I play minecraft. The items are not being dropped, smelted, etc. They are being cleared from my inventory as I empty items from the furnace

It does look the same except it's on both the latest iOS and the latest Minecraft. I know this has been happening for months but I recently picked MC back up, and this crap is still happening.

This exact thing is happening to me as well. Glad I'm not the only one

I have command block output already set to true, and I just tested logAdminCommands to test your theory.

Again, fall damage reset my score, no command was displayed on screen, no details, nothing.

I would appreciate if someone would re-open this bug and not classify it as resolved. I'll post a video to prove it's not resolved if necessary.

How is that not a minecraft command? None of my command blocks or the scoreboard have anything to do with fall damage.

Fall damage is resetting the score of kills to zero. Like I said, this is clearly not a command block problem. None of the command blocks run without a pressure plate too. No loops, no server-checking blocks, nothing. So again, nothing would modify the score for no reason. And out of the blue, when you receive fall damage, the score is reset to zero.
