Is RNG in Barotrauma kinda bugged?

[pks]

Today, doing a mission in the SP campaign, I looted at least 25 crawlers, mudraptors and spinelings with a xenologist medic. None of them dropped genetic material.

The chance of that happening at random is less than 1 in 250.

I got loads of genetic material before, and I did it "as usual". No new mods or anything (and those I have should not interfere anyway). I just did a couple of test runs (same everything) and got normal 1 UGM in 4 corpses loot.

Did anyone else notice something like this happening? I think I saw something like this with a mechanic not getting nowhere enough free mats, but it wasn't that obvious and I didn't pay attention.

Maybe the chance has been decreased, or maybe you've just been lucky before.
1 in 250 is 0.4% chance. That's not a lot. And you'd think that if you were to loot 250 creatures, you'd get at least 1 material, but that's not how probabilities work.

If it were, I'd be pretty wealthy in Raid Shadow Legends lol.


Anyway, some character skills help increase the chance.
The medic has the Gene Harvester which can increase it by 35% when killing enemies.
For the alien ruins, the medic has Researcher's Intuition which has 50% increased chance of additional items in containers (think extra genes in gene chambers).

Security has Deep Sea Slayer to increase drop chance of additional material by 40% when killing.


So mix medic and security together for highest chances.

You need to loot the creatures with the medic with the trait, and they should be the first character to attempt grabbing/looting the creature. I'm pretty sure the talent looting thing doesn't necessarily work unless you had it before the round began, too.

Clearly, you are functionally illiterate.

Duh. Imagine that!
0.378% is a probability of NOT getting any UGMs from looting 25 monsters with 20% spawn chance per monster. That's how probabilities work, buddy.

just killed 4 hammerheads and loot 3 gen mats from them.

Happy for you. Now, what this has to do with my question?

Great replies to people trying to help! Bravo!

Your save-file is probably hard corrupted and it's probably your fault :)

Best of luck!

I don't need "help" from useless nimwits who didn't even read the question.

Try again.

Yes, it's not just you. Haven't been able to figure out a reason though. Might be that swarms that spawn during events or missions have less loot, or it's just a bug. Can't really gauge which it is since mowing down a dozen crawlers for equal amount of husk eggs or alien blood would be... little too easy? So I could see it being intended as well.

Larger creatures have always had loot on them as far as I recall, it's just the smaller things. --> Loot the hammerheads, not the crawlers, unless they literally drop in your way.

[GHA!]

it might just be rng, 1/250 isn't that low.

if we look at it this way. barotrama har a averige of about 5500 players on a any time, if we think that a round takes about 30min then there are 264 000 rounds getting compleated every day. if 1/100 of runs has a medic looting 25 crawlers then there are 2 640 instances of that happening every day, then the chance of atleast one getting bad luck is 0.999975. this does not answer your question, and i did pull the 1/100 statistic from nowhere, but it does show that it's very likeley that atleast someone has your bad luck, and that someone seems to be you.

someone getting bad rng are also somewhat likely to make a post in this forum about it, and while that does also not answer your question. it does explain why a question about rng is even posted here.

I looted hammerheads, mudraptors, spinelings apart from crawlers. Both mission targets and regular spawn. I killed and looted every living thing in the level, and I ended up with 25 Alien Bloods, plus some spines, raptor eggs, bladders etc. in the airlock storage.

Come to think of it, there was more than 25, since many didn't drop any Blood.

Such a string is possible but unlikely, and RNGs do have a certain reputation.

A string of 25 empty monsters in a row in itself may be discounted as bad luck indeed. But the probability of such a string being entirely confined to a single mission is orders of magnitude less likely.

yet the way i thought about it was verry close, and related to the 1/100 stastistic i pulled from thin air, all you would have to do is replace the 1/100 thing and replace it with the ratio of missions of a medic looting exactly 25 crawlers in a row. is it 1 out of every 100? or perhaps 1000? anyways, the point is that the likleyhood of someone getting bad luck out on one of thier mission out of every player of this game is big, and thinking that rng is bugged due to this is just not understanding rng. altough it might feel unfair to be in the bad end of normal distrebution

i guess if anything what we should take away from this is that more games need pitty systems

Nah, buying from outposts should be enough. It won't bankrupt the crew to straight out buy a box of pulse laser fuel or a bunch of alien blood... or at least it shouldn't. In the later biomes the team will have to stockpile a bit more so they don't run out. Jovian radiation is no longer enabled by default but the last time I played campaign with that we had no problems with resource economy and I don't think that's changed too much.

I frequently play Medic and always go down the Xenologist route first and I have to agree that my rate of finding genetic material seems a hell of a lot lower than 20%. I notice Scavenger proccing when I take that, I notice Miner proccing, but when I pick Gene Harvester I feel like I still never find anything.

Well, the chance of failure to loot anything in a string of 25 at 20% spawn chance is 80%^25 = 0.38%; and the chance for these 25 failures in a row to happen within a single mission (as opposed to this string beginning in one mission and ending in the next) would be (with most simplistic assumptions) 1/25th of that, or 0.015% - i.e. once in ~6600 looter medic missions.

Which is exactly why I am asking this specific question here - to validate a suspicion.

With bots constantly getting stuck on ladders, cargo scooters vanishing, and minerals spawning inside walls - why wouldn't I expect a bug anyway? I've seen weirder bugs in games and even debugged some.
