Bug or Intended? Cob doesn't always drop when broken

[NoxxyGizmo]

I will block the door to my cellar with cob (early game). I've noticed that when I break the two blocks, sometimes I only get one back. I tried to do some testing with cob specifically and it was a little hard to reproduce on purpose. I think it has something to do with if you pick up an item at the same time you break a block, then you get the block you picked up, but the block you broke doesn't drop.

I'm not sure if this issue is spread to other types of blocks as well, but I've caught it happening multiple times on accident with cob specifically and was able to manually induce it once. It seems like a bug, but I could also see it being a "drops aren't guaranteed 100%" type of thing. If it's the latter, though, I feel like there should be some mention of it in the handbook.

You should get two pieces of cob if you break two pieces of cob.
EDIT: The above is a load of fluff. See post below.

Going to rapid fire some points to check out to help with the background.

* New game or an old one?
* Multiplayer server?
* Mods?
* "Error" in the logs at the time such as "Critical error" or "System.NullReferenceException: Object reference not set to an instance of an object."?
* Windows/Linux?
* Current game version?
* Server overloaded message at top right?
* Does decreasing View distance reduce frequency?

My first thoughts are either "server overloaded" or "mod interaction." 
"Bug" would be further down the list. But if it is partially reproducible and it's none of the above, load up your logs to the Issue Tracker with the time stamp and block name.

I'm not sure which log file I should be looking at but I scanned through and didn't see anything that looks like that. I zipped the log folder and attached it. I remember it happened twice right before I made my initial post which would make it 11/25 ~1:00pm (logs are now removed under advisement)

Thank you for helping troubleshoot

No, I'm pretty sure cob is much like mudbrick -- it returns less than 1 block. 0.7, I think, but it's been a long time since I looked.

Huh. I bow to @Thorfinn's superior game knowledge.

I just tried this on a test world with 100 Cob blocks and a flint shovel, on v1.21.5.

When broken in my case, it returned 83 Cob blocks and used 100 shovel durability.

It appears you don't get the full amount of Cob blocks back

EDIT: I did a real quick check of your logs - you may want to remove them from here now - and did not find any issues.
I can see where you are moving Cob around (eg "Moved 22xCob to (22x into backpack)"), but there are no errors or other activies in the other logs near these times.

I was misremembering. It returns 0.85.

	drops: [ {
		type: "block",
		code: "cob-none",
		quantity: { avg: 0.85, var: 0 }

0.83 was pretty darned close!

Thank you both! Mystery solved!

Also thank you for the advice, I removed the logs from my previous message
